Generators in JavaScript

 Generators in JavaScript

Generators are a feature in JavaScript that allow you to define functions that can be paused and resumed. Generators are useful for writing iterators, which are objects that can produce a sequence of values.

Here's an example of how to use generators in JavaScript:

javascript

function* fibonacci() {

  let a = 0;

  let b = 1;

  

  while (true) {

    let temp = a;

    a = b;

    b = temp + b;

    yield a;

  }

}

const fib = fibonacci();

for (let i = 0; i < 10; i++) {

  console.log(fib.next().value);

}

This code defines a generator function that produces the Fibonacci sequence and uses a for loop to print the first 10 numbers in the sequence.
