while loop to iterate javascirt code example

Example 1: Iterate with Do While Loops Javascript

var myArray = [];

var i = 10;

 do {  // The do while loop will always run atleast once before checking the condtion. This will return false and break out of the loop.
	myArray.push(i);
    i++;
} while (i < 5)

console.log(i, myArray);

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 ]
