JavaScript & Ajax

  1. Messing with Javascript

    Hey all,
    I've been fiddling with JavaScript and decided to share a neat little thing (its completely useless).

    Finished Code
    Code:
    console.log(+[[-~[]<<~[]][+[]]+[]][+[]][++[[]][+[]]+[+[]]]); //Prints 8
    Now for the break down -

    Pre-note - I use this function while playing with variables. It outputs the value and type of a variable. (The counter is to force the developer console to display each seperately)
    Code:
    var counter = 0;
    ...
  2. document.getElementById shortcut

    I'm amazed at how many people don't use a very simple shortcut for document.getElementById. This is for all the people who don't use a javascript library like jQuery.

    All you have to do is include this code somewhere on your page

    Code:
    function $(element) {
    return document.getElementById(element);
    }
    Then when you want to use document.getElementById('id'); just type $('id'); instead.

    Example

    Code:
    <html>
    ...
