Dart vs JavaScript vs Python: What are the differences?

Key Differences between Dart, JavaScript, and Python

Syntax: Dart is a statically typed language with a syntax similar to Java or JavaScript. It uses semicolons as line terminators and curly braces for blocks of code. JavaScript, on the other hand, is a dynamically typed language with a C-like syntax. It uses semicolons as line terminators and curly braces for blocks of code as well. Python, however, uses indentation to define blocks of code, making it easy to read and understand.
Type System: Dart has a strong static type system, meaning that variables are explicitly declared with their data types. JavaScript, on the other hand, has a weak dynamic type system, where variables can hold values of any type. Python, similar to JavaScript, also has a weak dynamic type system.
Performance: Dart is compiled to native code, which can result in faster execution and better performance compared to JavaScript and Python, which are interpreted languages. Dart's performance is also optimized for mobile, web, and server-side applications. JavaScript, being the language of the web, is designed to run in web browsers and has limited support for mobile and server applications. Python, on the other hand, is commonly used for server-side scripting and data analysis, but may not be as performant as Dart or JavaScript.
Tooling and Development Experience: Dart comes with a rich set of libraries and tools that offer great development experience and productivity. It has a package manager called Pub, which allows easy management of dependencies. JavaScript has a wide range of libraries and frameworks available, making it a popular choice for web development. Python also has a strong ecosystem of libraries and tools for various domains such as web development, scientific computing, and data analysis.
Scalability and Concurrency: Dart is designed to be scalable and support concurrent programming with isolates, which are lightweight threads that can communicate with each other. JavaScript, on the other hand, has limited support for concurrency and relies on callback functions and promises for asynchronous programming. Python has support for concurrency through threads and processes, but it has some limitations due to the Global Interpreter Lock (GIL).
Platform Support: Dart primarily targets web, mobile, and desktop applications. It can be used to develop cross-platform mobile apps using the Flutter framework. JavaScript is the de facto language for web development and is supported on almost all web browsers. Python is widely used in various domains, including web development, scripting, data analysis, and machine learning. It is supported on different platforms and has a large community of developers.

In Summary, Dart offers a statically typed, performant, and scalable alternative to JavaScript and Python for web, mobile, and server-side applications with a rich set of tools and libraries.

In December we successfully flipped around half a billion monthly API requests from our Ruby on Rails application to some new Python 3 applications. Our Head of Engineering has written a great article as to why we decided to transition from Ruby on Rails to Python 3! Read more about it in the link below.

Needs adviceon

React Native

Python

Flutter

I've been juggling with an app idea and am clueless about how to build it.

A little about the app:

Social network type app ,
Users can create different directories, in those directories post images and/or text that'll be shared on a public dashboard .

Directory creation is the main point of this app. Besides there'll be rooms(groups),chatting system, search operations similar to instagram,push notifications

I have two options:

@{React Native}|tool:2699|, @{Python}|tool:993|, AWS stack or
@{Flutter}|tool:7180|, @{Go}|tool:1005| ( I don't know what stack or tools to use)

We decided to use python to write our ETLs and import them into metabase via a lambda. Before python we tried using Go, but overall go was way more verbose than Python when writing the ETLs. Go also had some issues managing memory when using the S3 upload manager library. This was a deal breaker for us that made us switch to Python.

In the end the solution was much cleaner and maintainable.

Detailed Comparison

Python	JavaScript	Dart
Python is a general purpose programming language created by Guido Van Rossum. Python is most praised for its elegant syntax and readable code, if you are just beginning your programming career python suits you best.	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.	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.

What are some alternatives to Python, JavaScript, Dart?

PHP

Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world.

Ruby

Ruby is a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.

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!

Golang

Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.

HTML5

HTML5 is a core technology markup language of the Internet used for structuring and presenting content for the World Wide Web. As of October 2014 this is the final and complete fifth revision of the HTML standard of the World Wide Web Consortium (W3C). The previous version, HTML 4, was standardised in 1997.

C#

C# (pronounced "See Sharp") is a simple, modern, object-oriented, and type-safe programming language. C# has its roots in the C family of languages and will be immediately familiar to C, C++, Java, and JavaScript programmers.

Scala

Scala is an acronym for “Scalable Language”. This means that Scala grows with you. You can play with it by typing one-line expressions and observing the results. But you can also rely on it for large mission critical systems, as many companies, including Twitter, LinkedIn, or Intel do. To some, Scala feels like a scripting language. Its syntax is concise and low ceremony; its types get out of the way because the compiler can infer them.

Elixir

Elixir leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems, while also being successfully used in web development and the embedded software domain.

Swift

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.

Rust

Rust is a systems programming language that combines strong compile-time correctness guarantees with fast performance. It improves upon the ideas of other systems languages like C++ by providing guaranteed memory safety (no crashes, no data races) and complete control over the lifecycle of memory.
