Avoid transpilers like Babel and Bublé (and if you're using TypeScript, target a modern version of JavaScript)

can you not also use a .babelrc?

Babel is a complex system which requires considerable effort and knowledge to get working. I believe full legacy Edge compatibility can be reached simply by adding a single Buble transform to the rollup/webpack config.

Snowpack uses Babel for transpiling TS to JS, because Babel is much faster than TS compiler. The reason for that is that Babel only strips out the types and does not do any type checking.

What once began as a humble side project on Reddit, which you can see here, has now grown so much that it has fundamentally transformed how we build and develop Node.js applications.

Whereas Webpack bundles all our JavaScript source code files into one bundle (including custom configured build steps), Babel enables us to use recent JavaScript features that are not supported by many browsers yet.

to have sprung from some common source,

npm install eslint-loader --save-dev

The great disorder

generate(ast, null, code);

A stub-only implementation of Babel =================================== Babel is a loop-avoiding distance vector protocol that is suitable for both wired and wireless networks documented in RFC 6126.
