Remove falsy values

In this coding challenge, you will be implementing a function removeFalsey(arr) that accepts an array arr and returns a new array containing only the truthy values. A value is considered truthy if it is NOT one of the following: false, null, undefined, 0, NaN, or an empty string.

Instructions

• The input array may contain any number of values, including zero.
• The returned array should only contain truthy values.
• The original input array should not be modified.

Example test cases

const arr = [0, 1, false, 2, '', 3];
const result = removeFalsy(arr);
console.log(result); // should log [1, 2, 3]
