Standalone build of Babel for use in browsers and other non-Node.js environments

 @babel/standalone provides a standalone build of Babel for use in browsers
 and other non-Node.js environments.If you're using Babel in production, you
 should normally not use @babel/standalone. Instead, you should use a build
 system running on Node.js, such as Webpack, Rollup, or Parcel, to transpile
 your JS ahead of time.
 .
 However, there are some valid use cases for @babel/standalone:
  * It provides an easy, convenient way to prototype with Babel. Using
    @babel/standalone, you can get started using Babel with just a simple
    script tag in your HTML.
  * Sites that compile user-provided JavaScript in real-time, like JSFiddle,
    JS Bin, the REPL on the Babel site, JSitor, etc.
  * Apps that embed a JavaScript engine such as V8 directly, and want to use
    Babel for compilation
  * Apps that want to use JavaScript as a scripting language for extending the
    app itself, including all the goodies that ES2015 provides.
  * Other non-Node.js environments (ReactJS.NET, ruby-babel-transpiler,
    php-babel-transpiler, etc).
