What are generators in JavaScript?

Generators are special functions that can pause and resume execution, allowing you to manage asynchronous operations more easily.

How do I create a generator function?

You create a generator function using the function* syntax. Inside, you use the yield keyword to pause execution.

Can you give me an example of a generator?

Sure! Here's a simple example:

function* countUpTo(max) {
  let count = 1;
  while (count <= max) {
    yield count;
    count++;
  }
}

This generator will yield numbers from 1 to the specified max.

What are the benefits of using generators?

Generators help manage asynchronous code, reduce memory usage, and make it easier to work with sequences of data.
