Add all values in an array JavaScript/jquery

<div id="timeCalac">Click me to calculate your average time</div>

myData = [34, 67, 78];
var arrayTotalValue = 0;

$("#timeCalac").click(function () {
    // arrayTotalValue = add value of myData array function
    arrayTotalValue = arrayTotalValue/myData.length;
    $("#timeCalac").html(arrayTotalValue);    
});

I am making a function that records how long it took for the user to click on a element I then use the .push() command to add this number to the myData array. Is there a JavaScript or jQuery function that can add the value of the myData array and then store it in the arrayTotalValue variable.

There is no specific function to sum the values of an array, however you can use reduce() to achieve it:

myData = [34, 67, 78];
var arrayTotalValue = 0;

$("#timeCalac").click(function () {
    arrayTotalValue = myData.reduce(function(a, b) {
        return a + b;
    });
    $(this).html(arrayTotalValue);    
});
