What are generator functions in JavaScript?

Can you explain what generator functions are in JavaScript?

Sure! Generator functions are a special type of function that can be paused and resumed, allowing you to control the flow of execution.

How do you define a generator function?

You define 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 function?

Absolutely! Here's a simple example:

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

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

What are some use cases for generator functions?

Generator functions are great for handling asynchronous programming, creating iterators, and managing state in a more readable way.
