“Loops” memo. Part 2

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;
