The Best Way to Learn JavaScript,and Become A Professional

Start with how to add JS to html and what’s the difference between async and defer ? and then move to variable, data types, loops and conditionals, functions, anonymous functions, closures, arrays and associative arrays, events, regular expressions, promises, in the exact order.

This is how I learned JavaScript(JS) back in the day, and I hope it’ll help you as well

1- JavaScript Basics

So this is the most fundamental and most important part and first step of path to JS learning.

Start with how to add JS to html and what’s the difference between async and defer ? and then move to variable, data types, loops and conditionals, functions, anonymous functions, closures, arrays and associative arrays, events, regular expressions, promises, in the exact order.

Maybe, I have missed a few topics in here, but you’ll stumble on them along the way any way.

Also, learn how to debug with Chrome DevTools, because Chrome DevTool is the best in the business.

2- Object-Oriented Programming

After you have the strong foundation of the JavaScript Basics, perhaps you should move to OOP concept.

I would say OOP is the most important concept in the JS or any other programming language.

OOP in JS is based on prototype inheritance, unlike object or class inheritance in Java or C++.

Perhaps, move to meta programming after OOP, its not the most important part of JS but its nice to know, because believe me you don’t want Javascript to surprise you.

3- Testing and QA

Testing your code is as important as debugging.

You might’ve heard of words like TDD or BDD.

TDD(Test driven development) is the concept of programming where you write automated failing tests before you write your actual codes.

I know it sounds all weird, but believe me you’ll prefer TDD development over BDD ( Behaviour driven development).

BDD is the contrary to TDD.

When you’ll be working with big projects, testing is really important for your code, to work the way you expect it to.

It gives you that satisfaction and sense of security.

One of my favourite tool to test JS is *Jasmine *. Its really simple and most effective way to test your codes.
