how do an infinite loop in javascript

Question

Im trying to do an infinite loop using while between 0 to 100 and 100 to 0, but the browser crashes. There is a way to clear the browser memory? This is my code:

Answer 1

An infinite while loop will block the main thread wich is equivalent to a crash. You could use a selfcalling function ( wich leaves the main thread doing some other stuff inbetween):

(function main(counter){
    console.log(counter);
    setTimeout(main,0,counter+1);
})(0);

You can put a loop that goes from 0 to 100, and one that goes from 100 to 0 into it, without blocking the browser too much:

(function main(){
    for(var counter=0;counter<100;counter++){
       console.log(counter);
    }
   console.log(100);
    while(counter){
       console.log(--counter);
    }
    setTimeout(main,0);
})();
