ES6 vs JavaScript: What are the differences?

What is ES6? The next version of JavaScript. Goals for ECMAScript 2015 include providing better support for large applications, library creation, and for use of ECMAScript as a compilation target for other languages. Some of its major enhancements include modules, class declarations, lexical block scoping, iterators and generators, promises for asynchronous programming, destructuring patterns, and proper tail calls.

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.

ES6 and JavaScript belong to "Languages" category of the tech stack.

"ES6 code is shorter than traditional JS" is the top reason why over 98 developers like ES6, while over 1556 developers mention "Can be used on frontend/backend" as the leading cause for choosing JavaScript.

According to the StackShare community, JavaScript has a broader approval, being mentioned in 5080 company stacks & 6472 developers stacks; compared to ES6, which is listed in 1461 company stacks and 1725 developer stacks.

    CoffeeScript
    CoffeeScript is a little language that compiles into JavaScript. Underneath that awkward Java-esque patina, JavaScript has always had a gorgeous heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way.
    TypeScript
    TypeScript is a language for application-scale JavaScript development. It's a typed superset of JavaScript that compiles to plain JavaScript.
    jQuery
    jQuery is a cross-platform JavaScript library designed to simplify the client-side scripting of HTML.

    How developers use ES6 and JavaScript
    Avatar of Andrew Faulkner
    Andrew Faulkner uses JavaScriptJavaScript

    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).

    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.

    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".

    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!

    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).

    We started using CoffeeScript years ago, so the switch to ES6 is quite natural in our team. ES6 of course advances the JS standard to a level of an advanced language. We are using it today simply because it: 1. helps to keep the code shorter, 2. integrates easily with JSX, 3. helps to deal with immutable using const.

    ES6 is a new-ish, modern form of JavaScript that adds in extra functionality that make code cleaner and easier to work with, such as arrow functions, const and let declarations, array helper methods, object/array destructuring etc.

    ES6 (ES2015) is a huge improvement to the javascript spec. These additions are heavily leveraged in React development, such as spread operators, fat arrow functions, and classes.

    ES6 brings some sweet features to the language. Our favourites are lambda-expressions, block-scoped consts and lets and Promises.

    ES6/ES2015+ makes JavaScript a pleasure to write. Arrow functions, template literals and ES modules especially. RIP CoffeeScript.
