By making the main source code an ES module placed in `mustache.mjs`, what used to be in `mustache.js` is now built based off of the ES module source inside `mustache.mjs`. This is done primarily to avoid breaking existing projects already using mustache.js, by keeping the UMD-version in `mustache.js` part of the git repository in addition to the minified version in `mustache.min.js`. After experiment with several compilers; - Babel - TypeScript - Rollup and examining their build output, [Rollup](https://rollupjs.org/) was chosen because of the UMD output it creates which closely resembles what we've historically had in the previous `mustache.js` source code. The contents of `.js | .min.js` files has been generated by running the following npm script: ``` $ npm run build ``` Also change linting w/eslint to target the `.mjs` file, since the output of rollup that ends up in the old `mustache.js` file is not sensible to do linting on.
