/**
 * Immutably pads the array with {size} number of {item}
 *
 * @since v0.0.1
 * @category Array
 * @template {T} - The type of the array
 * @param {T[]} array - The original array
 * @param {number} size - The size of the pad; if greater than zero, the padding will go to the end of the array; if less than zero, the padding will go to the front
 * @param {T} [item] - The item to put in each index of the array
 * @returns {T[]}
 * @example
 * pad([1, 2, 3], 2) //=> [1, 2, 3, undefined, undefined]
 * pad([1, 2, 3], -2) //=> [undefined, undefined, 1, 2, 3]
 * pad([1, 2, 3], 1, 4) //=> [1, 2, 3, 4]
 * pad([1, 2, 3], -1, 0) //=> [0, 1, 2, 3]
