Why Should you learn JavaScript ?

JavaScript has become an essential web technology along with HTML and CSS, as most browsers implement JavaScript. Furthermore, JavaScript usage has now extended to mobile app development, desktop app development, and game development. All in all, it has exploded in popularity and is now a very useful skill to learn.

The merits of using JavaScript are :
Less server interaction : You can validate user input before sending the page off to the server. This saves server traffic, which means less load on your server.

Client-side validation

Dynamic drop-down menus

Displaying date and time

Displaying pop-up windows and dialog boxes

Displaying clocks etc

Handling DOM & BOM.

Immediate feedback to the visitors : They don't have to wait for a page reload to see if they have forgotten to enter something..

Increased interactivity : You can create interfaces that react when the user hovers over them with a mouse or activates them via the keyboard..

Richer interfaces : You can use JavaScript to include such items as drag-and-drop components and sliders to give a Rich Interface to your site visitors.

JavaScript is not a programming language in strict sense. Instead, it is a scripting language because it uses the browser to do the dirty work. If you command an image to be replaced by another one, JavaScript tells the browser to go do it. Because the browser actually does the work, you only need to pull some strings by writing some relatively easy lines of code. That’s what makes JavaScript an easy language to start with.

Secondly, and more importantly, there are the browser differences. Though modern web browsers all support JavaScript, there is no sacred law that says they should support exactly the same JavaScript. A large part of this site is devoted to exploring and explaining these browser differences and finding ways to cope with them.

There’s no better time to learn JavaScript : You’ve made a smart choice, because JavaScript is the most popular programming language out there. This is no exaggeration. This popularity and growth means more jobs and opportunities than ever before.

Get access to fast support if you get stuck : There’s nothing worse than getting stuck ten hours into a course and not getting the help you need to continue. Getting stuck is part of the learning process. That’s why I’m here to answer every single question that comes my way.

I guarantee that this is the most up-to-date and engaging JavaScript course available, and it comes with a Udemy 30-day money-back guarantee.

I can’t wait to see you on the inside !
