JavaScript vs Swift: What are the differences?

What is JavaScript? Lightweight, interpreted, object-oriented language with first-class functions. JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.

What is Swift? An innovative new programming language for Cocoa and Cocoa Touch. Writing code is interactive and fun, the syntax is concise yet expressive, and apps run lightning-fast. Swift is ready for your next iOS and OS X project — or for addition into your current app — because Swift code works side-by-side with Objective-C.

JavaScript and Swift can be categorized as "Languages" tools.

"Can be used on frontend/backend", "It's everywhere" and "Lots of great frameworks" are the key factors why developers consider JavaScript; whereas "Ios", "Elegant" and "Not Objective-C" are the primary reasons why Swift is favored.

Swift is an open source tool with 48.2K GitHub stars and 7.71K GitHub forks. Here's a link to Swift's open source repository on GitHub.

reddit, Slack, and StackShare are some of the popular companies that use JavaScript, whereas Swift is used by Slack, Lyft, and Zillow. JavaScript has a broader approval, being mentioned in 5034 company stacks & 6258 developers stacks; compared to Swift, which is listed in 979 company stacks and 526 developer stacks.

I'm making my university community web service with a team. (6 members myself included)

And we decided to use JavaScript, HTML, CSS (for sure, it's the basic of websites) but couldn't decide for the back end part.

There are tons of languages, tools, etc., but I'm really new to programming, so I'd like to get some help to figure out what tools we need.

So my question is this: are there any good examples of web community services we can mimic the tools or get an insight from them?

Python
Django

Since you're following Python, I would recomend using Django as your main back-end language. If you know Python it would be a great experience. Django is well documented on their official website: https://www.djangoproject.com/ I would also use React for front-end as well. Also this article is worth reading, I think progressive web app is something worth learning these days: https://web.dev/progressive-web-apps/ Hope that helps :)

Since your team is already using JavaScript, there's a great number of examples for backend services written with NodeJS. I'd recommend using Firebase, or any backend as a service (you can use that term to find alternatives), for setting up your backend as it is much easier for newer people to understand and lets you focus on your core application logic, and not provisioning servers, databases, etc.

Since you're team is already using JavaScript, there are alot of examples and open source projects written with NodeJs, so I preffer this language in your backend application and also I am recommended using Mongo DB with It for saving data in it, and also for your frontend application I am recommanded using VueJs.

Hello, I am interested in learning how to program. I am a beginner, and many articles saying I should go with Python if I am new to programming. I considered Lua a long time ago, but for my career, I believe major programming languages should be better for me. I'm considering Python at this moment, but if you have other tools I should use, let me know.

Hi Otensia! I'd definitely recommend using the skills you've already got and building with JavaScript is a smart way to go these days. Most platform services have JavaScript/Node SDKs or NPM packages, many serverless platforms support Node in case you need to write any backend logic, and JavaScript is incredibly popular - meaning it will be easy to hire for, should you ever need to.

My advice would be "don't reinvent the wheel". If you already have a skill set that will work well to solve the problem at hand, and you don't need it for any other projects, don't spend the time jumping into a new language. If you're looking for an excuse to learn something new, it would be better to invest that time in learning a new platform/tool that compliments your knowledge of JavaScript. For this project, I might recommend using Netlify, Vercel, or Google Firebase to quickly and easily deploy your web app. If you need to add user authentication, there are great examples out there for Firebase Authentication, Auth0, or even Magic (a newcomer on the Auth scene, but very user friendly). All of these services work very well with a JavaScript-based application.

As you have knowledge of Javascript, I would go towards Vue/React in Frontend and Node (with suitable framework) with backend. From my point of view Java would be too bloated for suggested kind of an app. I myself use PHP as a backend a lot and React as frontend but moving thoughts towards full stack javascript world.

php is the best for beginners, and one of the best for web development at all, all the host servers can handle it, a basic knowledge in java is not enough for build a web site, but a basic knowledge in php is enough. learn php basics and oop and mvc design pattern or any framework like Laravel (optional), and javascript for frontend (a framework like React or Angular is optional but good) and you will build any web site you want.

We migrated from PHP to Angular/PHP to Angular/Node to React/Node/AWS Lambda. React/Node(Typescript)/Lambda seems to be good so far as we have developed few applications (large and small) using this stack so far. React/Node/Lambda is also good for mobile. If you are planning to use AWS, you can use the S3 bucket to store the frontend and Lambda or EC2 for backend APIs.

  • Client-Side: \ The form of our product is a web app because we would also provide a dashboard for displaying data and for some further purpose including data filtering and comparison. Hence, we would definitely use HTML5 for structuring the web, CSS3 for styling the web, and JavaScript for building the front-end logic. As for frameworks, we would use React because it is component-based that can keep our front-end code clean and organized. The virtual DOM of React also provides better efficiency in time when rendering the page. Furthermore, React has a greater number of users than Vue and Angular, thus have active communities for problem-spotting and problem-solving. We would also incorporate Bootstrap into our web app to provide an aesthetic user interface and thus to improve the user experience. The fact that Boostrap supports responsive site would also ease our workload if future adaptation for mobiles is needed.

A major part of our project includes visualizing the data through graphs and charts. We chose to use d3.js since it provides a wide selection of well-designed graphics and animations. As a library, it is also easy to use and be included in our UI. JavaScript which our team has experience with was also selected to integrate graphics from d3.js into the UI, as well as to integrate the UI with the backend system. Along with JavaScript, HTML5 and CSS 3 are also selected mostly for styling and formatting the webpage. These three languages are widely used which means that more support will be available, making the implementation process easier.

What are some alternatives to JavaScript and Swift?
TypeScript
TypeScript is a language for application-scale JavaScript development. It's a typed superset of JavaScript that compiles to plain JavaScript.
Node.js
Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.
Dart
Dart is a cohesive, scalable platform for building apps that run on the web (where you can use Polymer) or on servers (such as with Google Cloud Platform). Use the Dart language, libraries, and tools to write anything from simple scripts to full-featured apps.
CoffeeScript
It adds syntactic sugar inspired by Ruby, Python and Haskell in an effort to enhance JavaScript's brevity and readability. Specific additional features include list comprehension and de-structuring assignment.
Java
Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!

Review of
Swift

The performance of Swift is almost the same as that of C++, which is considered the fastest in algorithm calculation arithmetics. Apple had this idea in mind and worked to improve the speed of Swift. For example, Swift 2.0 has beaten C++ in several computation algorithms, such as Mandelbrot algorithm. Objective-C is slower because it contains C API legacy.

Swift is faster than Objective-C, because it removed the limitations of C language and has been improved with the help of advanced technologies that were unavailable when C was developed. As mentioned by Apple, Swift was originally designed to operate faster.

Despite the fact that languages are different, they both integrate, and work with Cocoa and Cocoa Touch APIs, for all Apple platforms. Therefore, a regular app-user would not recognize the difference in operating speed between Objective-C vs Swift. Speed also depends on a programmer’s level and capabilities, since a slow app can be written in Swift as well.

How developers use JavaScript and Swift
Andrew Faulkner uses
JavaScript

Almost the entire app was written in Javascript, with JSON-based configuration and data storage. The following components were written and/or configured with Javascript:

  • Most server-side scripts, all unit tests, all build tools, etc. were driven by NodeJS.
  • ExpressJS served as the 'backend' server framework.
  • MongoDB (which stores essential JSON) was the main database.
  • MongooseJS was used as the main ORM for communicating with the database, with KnexJS used for certain edge cases.
  • MochaJS, ChaiJS, and ExpectJS were used for unit testing.
  • Frontend builds were done with Gulp and Webpack.
  • Package management was done primarily with npm - with a few exceptions that required the use of Bower (also configured with JSON).
  • "Templating" was done with Javascript dialect JSX.
  • The frontend was build primarily with ReactJS (as the View) and Redux (as the Controller / Store / frontend model).
  • Configuration was done with json files.

The only notable exceptions were the use of SCSS (augmented by Compass) for styling, Bash for a few basic 'system chores' and CLI utilities required for development of the app (most notably git and heroku's CLI interface), and a bit of custom SQL for locations where the ORM extractions leaked (the app is DB-agnostic, but a bit of SQL was required to fill gaps in the ORMs when interfacing with Postgres).

OutSystems uses
JavaScript

Read more on how to extend the OutSystems UI with Javascript here.

OutSystems provides a very simple to use AJAX mechanism. However, developers can also use JavaScript extensively to customize how users interact with their applications, to create client side custom validations and dynamic behaviors, or even to create custom, very specific, AJAX interactions. For example, each application can have an application-wide defined JavaScript file or set of files included in resources. Page-specific JavaScript can also be defined.

Gorka Llona uses
JavaScript

This GNU/GPL licensed Javascript library allows you to draw complex organizational charts that can't be drawn using Google's tool or equivalents. Orgchart structures are specified with JSON and can be generated on-the-fly by server-side scripts and databases. Events can be attached to clicks over the boxes. Multiple options can be defined; look at the repo for examples. This 1300-code-lines software component with contributors from 8 countries (and others for which I have to integrate their works) appears in the first page of Google Search results when searching for "Javascript Organizational Chart Library".

Cloudcraft uses
JavaScript

JavaScript gets a bad rep, quite undeservedly so in my opinion. Today, JS is closer to functional languages than to the traditional-OO languages, and when used as such provides a great development experience. The pace of development is just picking up with transpilers like Babel making future advanced language features available to the masses today. At Cloudcraft.co, we write 100% of both the front-end (with React) and the backend (with Node.js) in Javascript, using the latest ES6 and even some ES7 features. This is not your grandfather's Javascript!

Lawrence Cheuk uses
Swift

iPhone app, a new born language, it may good but the IDE, xcode is bad compare with Visual Studio. It just like a baby. playground can only use without connect to other library...you can not do a simply refactor of renaming a variable. You can go to definition and find reference, but you can not go to implementation....I should write them on xcode not here basically it is not the fault of swift, but it tightly to it, unless you want to use a notepad to write it.

MOKA Analytics uses
JavaScript

The application front-end is written in JavaScript (ES6). We originally selected it over TypeScript because many library typings at the time were still flaky and the transpilation time was slow.

We are now re-considering TypeScript because 1) the tooling has improved significantly, and 2) and the root cause of the majority of our front-end bugs are related to typing (despite having PropTypes).

Refractal uses
Swift

Most of our newer apps are written completely in swift, with our older ones and some special cases using a mix of Swift and Objective-C, but with Swift 2, the language is pretty much a must-use. "guard" is <3.

Swift

Flutter is coded with Swift v.2.3 and can be run with Xcode v.8.2.1. To launch in Xcode 9.3, the code needs to be migrated to Swift 4.1
