 In most cases, Babel does a 1:1 transformation of input-file to output-file.  However,
 you may be dealing with AST constructed from multiple sources - JS files, templates, etc.
 If this is the case, and you want the sourcemaps to reflect the correct sources, you'll need

-First, each node with a `loc` property (which indicates that node's original placement in the

 ## Technical details
 
 The `runtime` transformer plugin does three things:
 
 * Automatically requires `babel-runtime/regenerator` when you use generators/async functions.
 * Automatically requires `babel-runtime/core-js` and maps ES6 static methods and built-ins.
-* Removes the inline babel helpers and uses the module `babel-runtime/helpers` instead.
+* Removes the inline Babel helpers and uses the module `babel-runtime/helpers` instead.
 
-What does this actually mean though? Basically, you can use built-ins such as `Promise`, `Set`, `Symbol` etc as well use all the Babel features that require a polyfill seamlessly, without global pollution, making it extremely suitable for libraries.
