javascript - How would you remove all objects from an array?

So, how would you remove all objects from an array.. My current code is:

            var array = [""];
            function add() {
                var input = document.getElementById("enterInput").value;
                array.push(input);


                var arrayOut = document.getElementById("output").innerHTML = array;
            }

            function clearit() {
                var length = array.length;
                array.splice(0, length, length);
                array.push("");
            }

Thanks, Noah..
(and yes, I have checked the console and no errors are returned.)

Answer

Just use

function clearit() {
    array = []; //or array = [""];
}
