js for loop and while loop syntax code example

Example 1: javascript while

var i=0;
while (i < 10) {
	console.log(i);
	i++;
}
//Alternatively, You could  break out of a loop like so:
var i=0;
while(true){
	i++;
	if(i===3){
		break;
	}
}

Example 2: Iterate with JavaScript While Loops

var ourArray = [];
var i = 0;
while(i < 5) {
  ourArray.push(i);
  i++;
} // 0 to 4 [ 0, 1, 2, 3, 4 ]

var myArray = [];
var i = 5;
while (i  >= 0) {
  myArray.push(i);
  i--;
} // 5 to 0 (reverse) [ 5, 4, 3, 2, 1, 0 ]
