Do…While Loop

The do…while statement creates a loop that executes a specified statement until the test condition evaluates to be false. The condition is evaluated after executing the statement. Syntax for do… while is

  1. do {
  2.   // statement
  3. } while (expression);

Lets for example see how to print numbers less than 10 using do...while loop:

  1. var i = 0;
  2. do {
  3.   document.write(i + " ");
  4.   i++; // incrementing i by 1
  5. } while (i < 10);

Note: i = i + 1 can be written i++.
