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.

    1. Client-side validation

    2. Dynamic drop-down menus

    3. Displaying date and time

    4. Displaying pop-up windows and dialog boxes

    5. Displaying clocks etc

    6. 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.

Maurice29 December 2020

Ein bisschen zu sehr ausführlich erklärt, was einen teils müder werden lässt. Insgesamt aber ein toller und hilfreicher Kurs.

Sameer8 December 2020

Every thing is good?? please add more sections in future because this course is only cover core JavaScript.. We need more advance topics...No one can learn total JavaScript in 10 hours.

Sach9 September 2020

I am an experienced developer who needed a beginner course in JavaScript. In the first few lessons, I felt that the instructor repeated the same thing over and over again including the need to know CSS and HTML. This made the course 10 hours. It could have been shorter. Also some explanations were confusing such as pre/post increment. All you need to know is WHEN the value is used. Is it used before it's incremented (pre-increment) or after (post-increment). The instructor used next line/same line which I thought was very confusing. the explanation of functions was very disappointing with no mention of function or variable scope. I gave it two stars because I did pick up few things about JavaScript here and there but I will need to find another beginner JavaScript course to fill in the gaps before moving on to an advanced course.

Hersi1 September 2019

Thank you Mr Kumar. This is really very good course. I like the way you explained the Arrays, Functions and Conditionals. I have taken 4 JavaScript courses with 4 different teachers, but this one was different indeed. Thank you again. Hersi.

Lakshmi20 August 2019

This is an awesome Tutorial, Beginners like me will definitely get good knowledge in Java Script, and the way you explained each and every Topic is really Nice & easy to Understand. I would definitely Suggest this Course to my Friends. Thank You Sir for the Detailed Tutorial.

As a complete newbie to web dev, I was overwhelmed with the prospect of getting my foot in the water. However, by keeping concepts at an application level, Praveen’s JavaScript was the perfect soft introduction. Surprisingly, by NOT going into in-depth detail, his pedagogical style eliminated all preconceptions I had about how difficult starting this new journey would be.

K.b.subramanyam23 July 2019

Praveen Sir is very good in explaining the behind the scenes working of javascript which really helps in understanding the concepts. fantablastic and enotmous explanation. I learn online everything about web development, but this is amazing . Thank's Praveen, you are my Hero.
