How to Become a Front-end Developer in 2022

Introduction to a front-end Developer

A front-end developer works on how to present information on an electronic screen. They design the layout and structure of how a website will appear for the users. One can also say that they mostly work on the user interface.

A user interface enables the user to view the information on the web. A front-end developer gets design from a website designer. Then they use coding to make the design work on the internet. A developer uses different programming languages such as HTML, CSS, and JavaScript to make them work on the internet. Other components of the front end of a website are DOM (Document Object Model), Frameworks such as Angular, React, jQuery, Vue.Js, Bootstrap, Semantic UI, Ember.js, and others.

A front-end developer should be skilled in various technologies that include programming languages, frameworks, types of websites, and best practices to develop a perfect website.

In this blog, we will talk about the fundamentals of front-end development and the baby steps toward the profession of a front-end developer.

We will cover topics such as what is a framework and how they work? Then there are various programming languages with their advantages and disadvantages. The delightful skills of a front-end developer to create a dynamic website. The types of jobs you can get as a front-end developer with a handsome salary. Let’s dive deeper now.

Must Know Front-End Languages for Developers

What does a programming language do? They let us communicate with the machines. For front-end development, a programmer must know HTML, CSS, and JavaScript. Some other languages to mention are TypeScript, Elm, and Swift.

HTML

It is a standard markup language to display a page of information using a web browser. A front-end developer writes HTML documents using its elements such as head, title, paragraph, heading, etc to display them as pages across the web. The following is an example of the ‘Hello World’ application and its code

The building block of this image is a set of HTML code called tags. HTML codes are written in a document using tags such as title, head, body, paragraph. These tags are represented as
Title:
Head: …….
Body:…. 

Here, the body is the entire length of the visible screen. Most of the information is stored in between body tags that include tables, images, graphics, audio, video, etc.

Advantages:

• HTML is very easy to learn and implement
• It is free
• It supports multiple browsers such as Chrome, Microsoft Edge, Firefox, Safari, etc.

Disadvantages:

• It does not offer enough dynamic components
• Limited capacity to display content, so it uses CSS to rely on displaying content on pages.

CSS

CSS was designed to separate two elements of a web page: The presentation of content and the actual content. A front-end developer can use CSS to design a web page with layout, colours, and fonts.

How does CSS work? While developing a website, some of the CSS is stored on a separate .css file to provide style to the web pages. A CSS file defines different parts of a web page like fonts, alignment, size, layout, borders spacing, and other characteristics. This improves content accessibility, and flexibility, and reduces complexity and repetition of code.

Advantages

• CSS saves a tremendous amount of time for developers
• The .css files are easier to maintain.

Disadvantages

• It has cross-browser problems. It means that .css files behave differently across browsers.

JavaScript

A front-end developer can create a commendable web page using HTML and CSS. In such cases, the developer can use JavaScript to extend the functionality of the web page.

Advantages

• JavaScript snippets are used in extending web page functionality

Trending Front-End Developer Skills in 2022

As we know, a front-end developer uses the design made by a web designer. They use coding to make them live on the internet.

This process requires knowledge and skills on various levels. Firstly, the skills of a particular language for coding. Secondly, the environment to code such as frameworks, text editors etc.

If we divide these tasks into small parts then a front-end developer should have the following skills:

• Design layouts based on UX.
• Style attractive pages to retain users
• State management of data and processes

Below are the steps that will help you start from scratch and grow.

1. HTML Skills

HTML defines the purpose and organisation of web content, making it the fundamental language for anyone wishing to work with the front end. You don’t have to be an HTML expert or be familiar with every tag. You might want to concentrate on the few key points listed below:

1. Learn the basic structure of an HTML document
2. Learn some tags such as , <body>, <title>, <head> etc
3. Add text and try to edit the HTML document
4. Move towards adding and properly formatting the HTML document with proper tags
5. Insert list, table, forms and hyperlinks using designated tags
6. Embed images and videos on the page
7. The next step is to style the document using CSS

2. CSS Skills

We need to use CSS (Cascading Style Sheets) to style and give the HTML life because, without CSS, web pages will only have a white background. The screen behaviour of HTML elements is specified by CSS.

The following are some key ideas: 

• CSS selectors (how to select a specific element or group in HTML);
• Units in CSS (pixels, percentage, em+rem, vh+vw);
• Positioning in CSS (static, relative, absolute, fixed and sticky)
• CSS box model;
• CSS Flexbox;
• CSS grids;
• CSS Frameworks

Below are some of the most popular frameworks.

• Tailwind CSS;
• Bootstrap 5;
• Materialize;

3. Learn JavaScript

By now, you know how to create beautiful websites using HTML and CSS. But to create a strong and functional website, Javascript is needed. Because as of 2022, 98% of websites use Javascript. 

Javascript can be used on both the front-end and back-end. This Javascript functionality offers the advantage to write the entire website using one language. This makes the development process smooth.

JavaScript is popular and loved on the web and every programmer who wants to break into this market should at least know about it. Below are the basics of JavaScript for you to learn:

Every front-end developer should at least be aware of JavaScript, which is popular and loved by everyone on the web. You can learn the JavaScript fundamentals listed below:

• Data Types, Variables, Loops, Functions, Strings, Arrays, Objects, Classes;
• DOM (Document Object Model);
• Difference between var, let, and const keywords;
• Array methods (map, filter, reduce, etc);
• ES6 (arrow functions, template literals, destructuring);
• Asynchronous programming (async/await) 

4. JavaScript Frameworks

JavaScript Frameworks offers libraries, boilerplates, and popular resources for developing a web application. In a sense, a framework makes the developer’s life easier.

Some of the most popular Javascript frameworks are React, Angular, and Vue.js. It is recommended to study them and choose only one. 

In a word, Vue and React are quite similar to each other. They have the same difficulty level. On the other hand, Angular has a long learning curve but offers useful features.
