    Javascript Unshift - Use Unshift to Put Items on the Front of an Array in Javascript



    i=new Array("Hi", "Hello", "Cheers", "Greetings");

    i.unshift("Good day");

    document.write(i);

    Which Prints:
    Good day,Hi,Hello,Cheers,Greetings

    -We create an array and name it i because we adore short names.
    -We use Javascript's built-in unshift method on our array.
    -We enclose what we want unshifted (put on the beginning) in quotation marks, unless it's also a variable. (see Copy and Paste Code below)
    -We use Javascript's built-in document.write command to print to the browser.




    Free Copy and Paste Javascript Code:

    <script type="text/javascript">
    <!--

    i=new Array("Hi", "Hello", "Cheers", "Greetings");
    j="Good Day";

    i.unshift(j);

    document.write(i);
    -->
    </script>
