Babel vs QuickJS: What are the differences?

## Key Differences between Babel and QuickJS

<Introduction>

1. **Programming language compatibility**: Babel primarily focuses on transpiling new ECMAScript features into older versions for compatibility, whereas QuickJS is a lightweight, embeddable JavaScript engine written in C. 
2. **Use case**: Babel is widely used for converting the ECMAScript 2015+ code into a backwards-compatible version that can run in older browsers, while QuickJS is often used for embedding JavaScript in applications where a small and efficient engine is required.
3. **Execution environment**: Babel operates as a compiler that translates code during the build process, mainly for web development, while QuickJS functions as an interpreter that allows running JavaScript code directly within an application.
4. **Modules and dependencies**: Babel supports module bundling and transpiling ES6 modules into a format compatible with browsers, whereas QuickJS does not have built-in support for module systems and relies on external tools for managing dependencies.
5. **Performance and size**: QuickJS is known for its high performance and small footprint, making it suitable for resource-constrained environments, while Babel's performance is dependent on the complexity of the transformations applied to the code.
6. **Community and development**: Babel has a large and active community contributing to its development and maintenance, while QuickJS is maintained by a smaller team with a focus on optimization and efficiency.

In Summary, Babel and QuickJS differ in terms of language compatibility, use case, execution environment, module handling, performance, and community support.

    What is Babel?

    Babel will turn your ES6+ code into ES5 friendly code, so you can start using it right now without waiting for browser support.

    What is QuickJS?

    It supports the ES2019 specification including modules, asynchronous generators and proxies. It optionally supports mathematical extensions such as big integers (BigInt), big floating point numbers (BigFloat) and operator overloading.

      What are some alternatives to Babel and QuickJS?
      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.
