Babel vs Closure Compiler: What are the differences?

Developers describe Babel as "Use next generation JavaScript, today". Babel will turn your ES6+ code into ES5 friendly code, so you can start using it right now without waiting for browser support. On the other hand, Closure Compiler is detailed as "A JavaScript checker and optimizer". The Closure Compiler is a tool for making JavaScript download and run faster. It is a true compiler for JavaScript. Instead of compiling from a source language to machine code, it compiles from JavaScript to better JavaScript. It parses your JavaScript, analyzes it, removes dead code and rewrites and minimizes what's left. It also checks syntax, variable references, and types, and warns about common JavaScript pitfalls.

Babel belongs to "JavaScript Compilers" category of the tech stack, while Closure Compiler can be primarily classified under "JavaScript Optimizers".

Some of the features offered by Babel are:

  • Array comprehensions
  • Arrow functions
  • Async functions

On the other hand, Closure Compiler provides the following key features:

  • parses JavaScript, analyzes it, removes dead code and rewrites and minimizes what's left
  • checks syntax, variable references, and types, and warns about common JavaScript pitfalls
  • transpiling some ECMAScript 6 code to ECMAScript 3

Babel and Closure Compiler are both open source tools. Babel with 33.5K GitHub stars and 3.57K forks on GitHub appears to be more popular than Closure Compiler with 4.99K GitHub stars and 918 GitHub forks.

What are some alternatives to Babel and Closure Compiler?
Webpack
A bundler for javascript and friends. Packs many modules into a few bundled assets. Code Splitting allows to load parts for the application on demand. Through "loaders" modules can be CommonJs, AMD, ES6 modules, CSS, Images, JSON, Coffeescript, LESS, ... and your custom stuff.
TypeScript
TypeScript is a language for application-scale JavaScript development. It's a typed superset of JavaScript that compiles to plain JavaScript.
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.
ESLint
A pluggable and configurable linter tool for identifying and reporting on patterns in JavaScript. Maintain your code quality with ease.
rollup
It is a module bundler for JavaScript which compiles small pieces of code into something larger and more complex, such as a library or application. It uses the new standardized format for code modules included in the ES6 revision of JavaScript, instead of previous idiosyncratic solutions such as CommonJS and AMD.
