/**

* @function abs

* @description This script will find the absolute value of a number.

* @param {number} num - The input integer

* @return {number} - Absolute number of num.

* @see https://en.wikipedia.org/wiki/Absolute_value

* @example abs(-10) = 10

* @example abs(50) = 50

* @example abs(0) = 0

const abs = (num) => {

const validNumber = +num // converted to number, also can use - Number(num)

if (Number.isNaN(validNumber) || typeof num === 'object') {

throw new TypeError('Argument is NaN - Not a Number')

}

return validNumber < 0 ? -validNumber : validNumber // if number is less than zero means negative, then it converted to positive. i.e., n = -2 = -(-2) = 2

}

export { abs }
