JavaScript in real life use???

[z3r0aCc3Ss]

How can we use JavaScript in real life?
I mean, we can develop games and some applications in JavaScript.
What else we can do with it? Or where it is used nowadays?
Is is still under development and new new versions are carried out like HTML 5?

The most useful use on websites is Ajax in my opinion. Dynamically updating a page instead of refreshing like it's 1995. Real life uses are plenty. GMail uses it, reddit.com does for adding/editing comments and things like that. Also collapsing/expanding trees of comments. That's not an Ajax thing, but it's a Javascript thing. It's often very useful to be able to manipulate the DOM "live" so to speak, instead of loading a new page for every change you make. That's what Javascript can do.

right, I also think Ajax is the thing that gave JS the right to exist, before JS was mostly used for stupid browser-related stuff nobody really needed ("you are using IE7, screen resolution 1280x1024"...wow, thanks, didn't knew that ).
now Ajax is everywhere, it didn't just made administration ifaces more comfy (like in Wordpress for example), it also gave us such nice overlay effects like in the suck-o image gallery...

Absolutely. Google's O3D API for creating 3D environments in your browser is Javascript.

JS is used practically everywhere.

while it has many case uses, its primary uses target UI based structures like menus, forms, modals, and the like - its mainly a front-end client based language, meaning javascript runs on your computer when you visit a website that is using it, thats why you can turn it off.

As some have mentioned, using it in AJAX is common as it allows for the execution of scripts asynchronously, like updating a page without a refresh etc...

A lot of ecommerce websites use Javascript to add items to your cart, other sites track usage statistics and traffic with it (google analytics).

There are also a myriad of awesome frameworks that make it easier to do things in JavaScript, notably - jQuery, mooTools, YUI.

Its uses can also extend from the Client side programming to Server side as well, an example may be node.js
