What are generator functions in JavaScript?

JavascriptWeb DevelopmentFront End Technology

Generator Functions allows execution of code in between when a function is exited and resumed later. So, generators can be used to manage flow control in a code. Cancel asynchronous operations easily since execution can be paused anytime.

Here’s the syntax; do not forget to add an asterisk after the “function” keyword. You can add an asterisk using any of the following −

function *myFunction() {}
// or
function* myFunction() {}
// or
function*myFunction() {}


Let’s see how to use a generator function

            var num = 1;
            while (num < 5)
            yield num++;
         var myGenerator = display();
