4-26 Free Code Camp remove all falsy

Remove all falsy values from an array.

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

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

Here are some helpful links:

Boolean Objects
Array.filter()

function bouncer(arr) {
  // Don't show a false ID to this bouncer.
  
  return arr.filter( function( value ){
        return value ? true : false;
    });
}

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


// other solution:

function bouncer(arr) {
    var truths = arr.filter(function(filterTrue) {
        return filterTrue;
    });
    return truths;
}

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

Another solution =)

function bouncer(arr) {
for (var i =0; i<arr.length; i++){
if (!arr[i]){
arr.splice(i,1);
i--;
}
}
return arr;
}

bouncer([false, null, 0, NaN, undefined, ""])
