Basic JavaScript (17/111) | Finding a Remainder in JavaScript | freeCodeCamp

The remainder operator % gives the remainder of the division of two numbers.

Example:
5 % 2 = 1 because
2 * 2 = 4
5 - 4 = 1 (Remainder)

Usage:
In mathematics, a number can be checked to be even or odd by checking the remainder of the division of the number by 2.

17 % 2 = 1 (17 is Odd)
48 % 2 = 0 (48 is Even)

Note:
The remainder operator is sometimes incorrectly referred to as the "modulus" operator. It is very similar to modulus, but does not work properly with negative numbers.
