How to understand that it is time to complicate the JavaScript code with asynchronous modules (RequireJS, ...)?

Question

JavaScript

At some point, the introduction of a new abstraction complicates the code less than if you continue to write in the old way.
A certain trigger must work for the programmer. Like, I write, I write, before that it was normal, but now I added lines and now it’s enough to complicate and duplicate, I’ll select a piece in the method. From simple to complex. Do not introduce new entities before necessary.
Asynchronous Modules (AMD) such as RequireJS help organize code in Javascript. But when should the trigger work, that it is time to complicate the system with them?

Answer 1

Yes, as it were ... always possible. If your code can be broken down into modules/components, then this is the time. It's not an abstraction, it's a module system. In production, the assembled version is usually laid out (what kind of r.js or browserify). ES6 is coming with its browser-supported module system out of the box.

Answer 2

If you are using any MV* library, then it's time.
