Hello guys, if you are a web developer and wondering what things you should learn in 2021 to take your skills to next level or someone who aspires to become a frontend developer in 2021, but not sure about which technologies, tools, framework, languages, and libraries to learn, then you have come to the right place.

In this article, I am going to share some of the most essential things a frontend developer should know.

Being an author of a technical blog, I often receive questions like what tools and technologies should a web developer learn? Which programming languages are suitable for web development, and what skills are necessary? I am going to answer all those questions from my reader in a series of blog posts, and this is the first one of them.

In this article, I am going to share the most essential things a web developer should know, which obviously includes the big three of Web development — HTML, CSS, and JavaScript, and several other useful tools that are essential but not mentioned or taught together.



If you are looking for surprises or shiny new technologies like Svelte.js or Vue.js, then I am sorry they are not part of this article, as I don’t think they are essential for all web developers.



They might be good for a seasoned web developer looking to learn a new JavaScript framework but not something a beginner should learn. Instead, this article is based upon my own practical experience and contains the most essential thing a Web developer should learn in 2021, mainly a frontend developer.

And, if you need a comprehensive course to become a web developer, I highly recommend The Complete 2020 Web Development Bootcamp course by Angela Yu on Udemy. It’s a great resource to become a full-stack web developer with just one course.

Btw, If you are an experienced web developer than I don’t want to disappoint you, and I’ll write about those new technologies, frameworks, and libraries in the coming days, and there we’ll see the benefits and wonders of learning new things, but for now, let’s focus on the most essential thing a Web developer should learn in 2021.

What should a Frontend Developer Learn in 2021?

Without wasting any more of your time, here is my list of things a web developer or anyone who wants to become a web developer should learn in 2021.



This list includes programming languages like javascript, markup language like HTML, styling tools like CSS, a framework like React, IDE like VSCode, tools like Chrome Developer Tools, NPM, and Webpack, and REST API tools like Postman and GraphQL, a better way to develop APIs.



I have also included Responsive web design as a skill because, in 2021, it’s almost given if you want to serve all of your audience accessing your website or web application using different devices.

1. HTML (HTML 5)

This is the first and foremost thing anyone serious about web development should learn. It’s probably the oldest web technology out there and also the first one I learned long ago, but it’s still relevant, and you just cannot become a Web Developer without a good knowledge of HTML. Technically it’s a markup language and used to specify the structure of your page.



Nowadays, it’s very rare for anyone to create a web page by writing HTML. Instead, most of the webpage you see is generated by an advanced framework like Angular and React. Still, if you want to understand, debug, and solve problems, you must know essential HTML tags like div, span, title, headers, etc.



Even if you know HTML, there is no harm in updating yourself with the latest development, and if you want to start from scratch, I suggest you join the Learn HTML 5 Programming from Scratch course on Udemy. It also covers CSS, which we’ll discuss next in the list.
