How long would it take to learn JavaScript?

Learning JavaScript will unlock gates to a ton of opportunities. Undoubtedly it is one of the most popular and in-demand programming languages.

If you are a beginner and learning JavaScript for the first time having good resources and a straightforward learning approach will help you to achieve your goal of learning JavaScript.

Why learn JavaScript?

Create Mobile Applications using react-native
Desktop Applications using electron.js
Train Artificial Intelligence Models using Tensorflow.js
Using ReactJS, we can create beautiful UIs for our websites
Using ThreeJS, we can add three-dimensional interactivity to our websites
Using the data visualization JavaScript libraries, we can nicely present the data

There are some other use cases where JavaScript comes to the rescue. We can create all those things just by learning JavaScript, so you can imagine how helpful and powerful JavaScript is.

Pre-requisites to learning JavaScript

You can start learning JavaScript without any programming experience. If you want to become a frontend developer and build and design some fabulous websites, then first learn HTML & CSS.

A basic overview of HTML & CSS also works and will help you create projects.

How long does it take to learn JavaScript for a beginner?

Let’s calculate how much time it will take you to learn if you are a complete beginner in programming or if you have some experience in programming.

Time required to learn JavaScript Fundamentals.
The time needed to learn JavaScript Intermediate concepts
The required time to learn JavaScript Advanced concepts

Let’s go with the basics first.

JavaScript basics

If you are coming from another programming language background, You will complete JS basics within 2 – 3 Days if you are busy.

You might take one week to understand the basics if you are a beginner.

Basic concepts include

Variables
Data Types
If else concepts
Difference between let, const, and var
Switch statements
Loops (For, while, and do while)
Functions

JavaScript Intermediate Concepts

2 – 3 days if you are coming from another programming language background.

Learning intermediate concepts will take one week if you are a beginner.

Intermediate concepts include

Functions methods ( closures, call, apply, and bind )
this keyword
Objects ( methods and iterables )
Arrays
Map & Set
Date
RegExp

Till now, you have learned enough to start building projects, and I suggest you start creating small projects, host them using a free hosting website and host your code on GitHub.

If you want to come out of tutorial hell and see real progress in your learning, you need to build projects and solve some logic-based problems.

JavaScript Advanced concepts

2-3 weeks if you come from another programming language background. And one month if you are a beginner.

Concepts like Prototypal inheritance, Object-oriented, and creating a class based on prototypes are tough to understand at a time.

You take your time and try to learn just one concept at a time and practice a lot on those concepts.

Advanced concepts include

JavaScript Classes (prototypal inheritance and static )
Async-await Functions
Call back functions
JavaScript Promises
Document Object Model (DOM).

I assume you are giving 2 – 4 hours daily to learn JavaScript. For a beginner, it will take one to two and a half months to learn and another month for building projects.

For someone with programming knowledge, it will take one to one and a half months.
