JavaScript do...while Loop

Previous Next

In JavaScript, a do...while loop executes a block of code at least once, and then repeatedly executes the block as long as a specified condition evaluates to true.

The do...while loop in JavaScript can be used to generate the cubes of numbers from 1 to 10.

Here's an example of generating the cubes of numbers from 1 to 10:


// Variable to store the starting number
var i = 1;
var cube = 0;

do {
  cube = i * i * i;
  document.write("<br>" + i + "<sup>3</sup> =" + cube);
  i++;
} while (i <= 10);

Explanation of the example:

var i = 1;: Initializes the starting number.
do { ... } while (i <= 10);: Executes the loop to calculate and display the cube of each number from 1 to 10.
i++;: Increments the number.
