Use For Loop and ES6 to remove falsy values from an Array

If you are using ES6 in your project, you can easily remove empty or falsy values from an array. It is the fastest way to do that.

const input_arr = [20, 30, , , , null, 50, 40, undefined, , null, undefined];
const result = [];

for (let i of input_arr)
    i && result.push(i);

console.log(result)

Output

[20,30,50,40]
