Return the truthy value or the last falsy value if none of the iteration returns truthy

Usage: someTruthy<T, R>(list: Array<T>, callback: (value: T, index: number, list: Array<T>) => R, reverse?: boolean): R

import { someTruthy } from 'some-truthy'

someTruthy([0, 1, 2], num => num) // Return the first truthy value it find

someTruthy([0, false, undefined, null], falsy => falsy) // Return the last falsy value it find if non of the given items is truthy
// Output: null
someTruthy([0, 1, 2], num => num, true) // The last argument is for iterates from right to left instead of left to right
