ESM modules in node: npm edition

The proposal you’re about to read is not just a proposal. We have a working implementation of almost everything we discussed here. We encourage you to checkout and build our branch: our fork, with the relevant branch selected. Building and using the implementation will give you a better understanding of what using it as a developer is like.

Our implementation ended up differing from the proposal on some minor points. As our last action item before making a PR, we’re writing documentation on what we did. While I loathe pointing to tests in lieu of documentation, they will be helpful until we complete writing docs: the unit tests.

This repo also contains a bundled version of npm that has a new command, asset. You can read the documentation for and goals of that comma

// See https://jsperf.com/acorn-top-level-parsing-experiment/1 for example  

acorn.plugins.top_level = function (instance) {
      // Could skip other things as well, but this
      // is where the most time can be saved
      instance.parseBlock = function () {
          var node = this.startNode();
          var length = this.context.length;
          do {
              this.next();

If you have images and you are showing them on the web using an <img> tag, you must ALWAYS include alt text.

If you are writing markdown, you have no excuse not to add alt text.

Doing this is lazy. You're better than that.
