While loop

Syntax

while (condition) { actions }

Actions will be executed again and again until the condition returns false.

Accumulation of values ​​in a loop

var sum = 0; var i = 0; while (i <= 5) { sum += 1; i++; console.log(i); }

The program will log:

LOG: 1 (number) LOG: 2 (number) LOG: 3 (number) LOG: 4 (number) LOG: 5 (number) LOG: 6 (number) // Loop body code will not be executed, the condition will return false

Calculating percentage of a number

The easiest way to find a percentage of the number is to divide the number by 100 and multiply by the percentage.

// Let’s calculate 2 percent of 100 1000 / 100 * 2 = 20; // Let’s calculate 7 percent of 1200 1200 / 100 * 7 = 84;
