    How can I run a javascript just from my computer? I'd like to test a script out.

    Simply create a web page and include the code. Save the file locally and double click it to open in your browser. If your script relies on certain elements being on the page then you'll have to add them.

    <!DOCTYPE html>
    <!-- put CSS links and meta tags here -->
    <!-- Any elements you need for your script to work -->
    <script src = "path to your script"></script>
    Depending on how you've written your script you may have to add an event handler to the body:

    <body onload="entryfunction()">
    Better is to use the IIFE (Immediately Invoked Function Expression) format at the foot of the page:

    (function (){
    // All your code here or call your entry function.

    If your code depends on other libraries such as jQuery, you can try it out online at

    You can then share it with other people if you want to show them about your code (e.g. to get help with it).

    Thanks I shared it with Dunmail and his response was:
    So, now I'm stuck because I how no clue how who to get ahold of for the script, or create a web page with buttons to call the functions.
