Scrambling a word into random letters

Question

The program is supposed to tank the word you entered into a box split it into an array of letters and shuffle them. After that it capitalizes the first letter and lowercase the rest and outputs that into the same box.

I am trying to scramble a word into random letters but I can't get past this error.

In chrome it said I have an unexpected Identifier and in mozilla it said i am missing a bracket for newWord = shuffle(newWord); *fixed

Edit : now i have an error saying that that capitalize is not a function.

    function Random() {
            for (var start = 0; start < n; start++) {
                var newWord = word.charAT(start)

                    newWord = shuffle(newWord);

                    function shuffle(array) {
                        var currentIndex = array.length,
                            temporaryValue, randomIndex;

                        while (0 !== currentIndex) {

                            randomIndex = Math.floor(Math.random() * currentIndex);
                            currentIndex -= 1;

                            temporaryValue = array[currentIndex];

This line:

var newWord = (word.charAT(start)

should be:

var newWord = word.charAt(start)

And, here's a much more simplified version of what you are trying to do:

 // Get a reference to the DOM element, not a property of the element // that way you can access another property later without having // to re-scan the DOM for the element again var txtWord = document.getElementById("word"); var btn = document.getElementById("submit"); // Set up your events using DOM standards and not inline HTML event attributes btn.addEventListener("click", random); // By convention, use camelCase for naming function random() { // Separate all the letters into an array var letterArray = txtWord.value.split(""); // create an new array from scrambled letters in the original array var scrambledArray = []; var len = letterArray.length; for (var start = 0; start < len; start++) { // Get a random number between 0 and the highest array index and put it in the new array var num = Math.floor(Math.random() * letterArray.length) scrambledArray.push(letterArray[num]); // Remove letter from original array letterArray.splice(num,1); } console.log(scrambledArray.join("")); }
