Remove all falsy values from an array.

• Falsy Values

Falsy is something which evaluates to FALSE. There are only six falsy values in JavaScript: undefined, null, NaN, 0, "" (empty string), and false of course.

try to solve the problem now

We need to make sure we have all the falsy values to compare, we can know it, maybe with a function with all the falsy values...

Then we need to add a filter() with the falsy values function...

Solution ahead!

function bouncer(arr) {
  return arr.filter(Boolean);
}

🚀 Run Code

The Array.prototype.filter method expects a function that returns a Boolean value which takes a single argument and returns true for truthy value or false for falsy value. Hence we pass the built-in Boolean function.
