Allow imports with .js extension

[cyrilletuzi]

Since TS 2.0, it's possible to :
import { Something } from './something.js';

Module identifiers allow for .js extension

Before TypeScript 2.0, a module identifier was always assumed to be extension-less; for instance, given an import as import d from "./moduleA.js", the compiler looked up the definition of "moduleA.js" in ./moduleA.js.ts or ./moduleA.js.d.ts. This made it hard to use bundling/loading tools like SystemJS that expect URI's in their module identifier.

With TypeScript 2.0, the compiler will look up definition of "moduleA.js" in ./moduleA.ts or ./moduleA.d.ts.

But using this possibility with awesome-typescript-loader results in error :
Module not found: Error: Can't resolve './something.js'

It's important to be compatible with ES6 modules, which require the .js extension, as <script type="module"></script> is now in test in all browsers, and as for now TS doesn't provide an option to add the .js extension in transpiled files (see microsoft/TypeScript#13422).

It's possible in rollup/rollup-plugin-typescript so I assume it's possible with awesome-typescript-loader too.

Unresolved, but closing as there has been no answer.
