How does a WHILE loop start?







The while statement creates a loop that is executed while a specified condition is true.

The while loop will continue to run as long as the condition is true. It will only stop when the condition becomes false.


while (condition) {
  code logic block to be executed

Loop through the indices of an array to collect the course names from the courses array:

var courses = ["HTML", "Javascript", "CSS", "Jquery", "HTML5"];
var text = "";
var i = 0;
while (i < courses.length) {
 text += courses[i] + "<br>";

The example above explained as follows:

  • First, we set a variable before the loop starts (var i = 0;)
  • Then, we define the condition for the loop to run. As long as the variable is less than the length of the array (which is 5), the loop will continue till the loop end.
  • Each time the loop executes, the variable is incremented by one (i++)
  • Once the variable is no longer less than 5 (array's length), the condition is false, and the loop will end
