* If number is divisible by 2 i.e remainder != 1, then it is even

* therefore, the function will return false

/**

* @function isOddBitwise

* @description -> Checking if number is even using bitwise operator

* Bitwise AND (&) compares the bits of the 32

* bit binary representations of the number and

* returns a number after comparing each bit:

*

* 0 & 0 -> 0

* 0 & 1 -> 0

* 1 & 0 -> 0

* 1 & 1 -> 1

*

* For every odd numbers, the last binary bit will be 1

* and for even numbers, the last binary bit will be 0.

*

* As the number is compared with one, all the

* other bits except the last will become 0. The

* last bit will be 0 for even numbers and 1 for

* odd numbers.

* @see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Bitwise_AND

* @param {number} number

* @returns {boolean}
