The Power of Javascript

Javascript is an incredible language originally intended to allow dynamic alterations to a webpage.

Javascript was extended by John Resig with JQuery, an extensive API designed to make Javascript easier to use and more accessible.

The major browsers are also constantly releasing updates that make Javascript run even faster, and is something they are competitively trying to improve.

This means that you can write an application in Javascript, and over time the browsers, and ever improving hardware will make the code run faster!

Javascript has appeared to have reached its limits so many times before, firstly allowing forms to have client side validation in the mid 1990’s. Then again early in 2000’s with dynamic HTML such as Image Galleries and other fancy effects.

But now, Javascript seems to have blown completely past all other “limitations” and achieved one of the most demanding tasks a computer system can do, by emulating another computer architecture.

If you search the net you will find video game system emulators from the 1980’s and 1990’s that run at perfect speed, and are completely playable.

And just to really show how Javascript has no upper limit, you can even get an x86 emulator in Javascript running a cut down version of Linux here: http://bellard.org/jslinux/index.html.

If this is what Javascript can do now, what will it be doing in 5 years time?
