Description

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

5 % 2 = 1 because
Math.floor(5 / 2) = 2 (Quotient)
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.

Instructions

Set remainder equal to the remainder of 11 divided by 3 using the remainder (%) operator.

Tests

tests:
  - text: The variable <code>remainder</code> should be initialized
    testString: assert(/var\s+?remainder/.test(code), 'The variable <code>remainder</code> should be initialized');
  - text: The value of <code>remainder</code> should be <code>2</code>
    testString: assert(remainder === 2, 'The value of <code>remainder</code> should be <code>2</code>');
  - text: You should use the <code>%</code> operator
    testString: assert(/\s+?remainder\s*?=\s*?.*%.*;/.test(code), 'You should use the <code>%</code> operator');

Challenge Seed

// Only change code below this line

var remainder;

After Test

(function(y){return 'remainder = '+y;})(remainder);

Solution

var remainder =  11 % 3;
