how to use while loop javascript 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: javascript count down with wile loop

//declare and instantiate your variable
var timer = 60;

//set up your loop that will run while your variable is greater than zero
while (timer > 0) {
//log timer to the console for debugging purposes
console.log(timer);
//reduce the count of timer by one over each iteration
timer--;
}

//after timer has reached zero, the code will break out of the while loop and run the alert with your confirmation message
alert("Done");

Example 3: while javascript

do {

    text += "The number is " + i;

    i++;

 }

while (i < 10);
