"JavaScript doesn't need more features; it just needs a couple of small things fixed" - Ryan Dahl

The CommonJS and AMD module syntaxes are unfriendly to each other, requiring boilerplate everywhere, which UMD tries to solve with more boilerplate.

The ES6 module syntax adds new keywords in strict mode, that then depend on a sharply modified cross-origin requests shims, and internal module management. An ES6 Module Transpiler aims to solve the not-yet-supporting environments problem with a source transformation step.

We don't need more syntax like imports x from 'x.js'. We don't need a module keyword that will break QUnit module() or Node.js modules.

No official CS education but I learned about readers-writer locks after implementing a mutex library. I happened to come across a real-world use case that I would need this for.

Say we have many people signing up to take a class, their payment (through Stripe, or whatever) might be in flight. And imagine the teacher cancels the class, which would trigger a refund event.

Without proper locking, the refund might fail to execute for those students whose payments are in flight at the time of the class cancelation.

First run this code:

const exec = () => {
   setTimeout(() => {
      throw 'nothing can catch this, except domains';
   },10);
};
