The kick start guide for javascript beginners.

If you are following the tech trends, then you probably come across the statement “Javascript is everywhere”. Yeah, you heard it right. Javascript is now everywhere and already started gaining attraction among clients and investors. It is the easiest and funniest programming language on the earth. Now it has the ability to run in browsers as well as servers with the help of Node JS. Adding to that, you can even develop mobile and desktop applications using javascript. Let’s get straight to the topic. Getting started with javascript is super easy as you need only a browser. By pressing “Ctrl +Shift + I” in windows or Linux and “CMD + Shift+ I” you can get developer tools where you can start writing code right away. Before you pass the halfway journey of Javascript (any other language), you must be familiar with the things below. Make sure you are familiar with these concepts before the deeper dive.

6. ES6 Features in Javascript.

ES6 features in javascript help in reducing the number of lines in the code and provides more understandability and readability to the code. Please click here to learn more about ES6 features in javascript.

With that being said, reading without trying is obviously trash and a waste of time. Get your hands dirty and happy coding. See you in my next story.
