I got it there is an input button

Your code is just evaluating your array, then throwing away the value. To print it out, use console.log.

function bouncer(arr) {
// Don't show a false ID to this bouncer.

return arr;
}

bouncer([7, "ate", "", false, 9]);

/*Remove all falsy values from an array.

Falsy values in JavaScript are false, null, 0, "", undefined, and NaN.

Hint: Try converting each value to a Boolean.

Remember to use Read-Search-Ask if you get stuck. Write your own code.*/
