How to determine if a number is odd in JavaScript

Question

Can anyone point me to some code to determine if a number in JavaScript is even or odd?

Answer 1

Like many languages, Javascript has a modulus operator %, that finds the remainder of division. If there is no remainder after division by 2, a number is even:

// this expression is true if "number" is even, false otherwise
(number % 2 == 0)

This is a very common idiom for testing for even integers.
