How to Master Front-End Development In 2020

What actually Front-End is?

Front-end is what actually you see on the browser. The user interface (UI), it’s UX, and everything you see on the browser is the website’s front-end.

Developers who focus on developing designing user-interfaces of websites are called Front-End Developers.

Front end developers will be engaged in analyzing code design and debugging application along with ensuring a seamless user experience.

You manage what people first see in their browsers. As a front end developer, you are responsible for the look and feel of the site

Then how to get started with Front-End Development?

In the web-industry, front-end development deals with how the user interacts with the web page. For example, when you want to buy some clothes, so you go to some shopping site.

Here you can filter the product according to the price(low to high/ high to low), color, brand, customer review, material, etc. If you want to buy a laptop, you can refine your search according to the processor, RAM, brand, graphic card (available or not), etc.

If you like any product, you can click to ‘Shop Now’ or ‘Buy Now’ or any other options like this. This whole process comes into the area of front-end development.

Here you don’t need to bother about back-end processes. For example, when you filter something, how it processes in the database and gives the output according to your search.

Let’s start with the Basics:

HTML stands for HyperText Markup Language. It was introduced by Tim Berners-Lee, a computer scientist, and inventor of the World Wide Web.

Though it contains ‘Language’ in its name, it is not a programming language. It is a markup language which means what will be the content on the web page.

The code used in formatting the text is called ‘Tags’. It is the backbone of the web page. With the HTML, one can make static web pages only, not dynamic.

Here content on the web page can be paragraphs, tables, forms, links, images or any other representations. The latest version of HTML is HTML5 and it was published on October 28, 2014.


CSS stands for Cascading Style Sheet. HTML doesn’t define how the content will be present on the web page. CSS was developed to present the content on the web page.

As the name suggests, it is used to style the web page. One can have a unique look of the site the way he/she wants. The latest version of CSS is CSS3.


Bootstrap is an HTML, CSS and JS framework to design websites faster and easier. It reduces codes. It has built-in classes to make the website responsive.

One doesn’t need to write excessive lines of CSS. For example, if you want to divide the page into three columns equally, you have to write the number of lines in CSS. With bootstrap, it can be done easily just by using built-in classes.

javascript is the programming language to make the web page dynamic. It is a client-side language. It uses the Document Object Model (DOM) to manipulate the web page in response to the events/user input.

It defines the behavior of the web page. Using the technique called AJAX (Asynchronous JavaScript and XML), one can get, post, update and delete data without reloading the page.

As the name says, it allows web pages to be updated asynchronously. With AJAX, it is possible to update the part of a web page without refreshing the whole page.


jquery is a javascript library. It was designed to simplify HTML DOM, event handling, CSS animation, and AJAX. It was invented by John Resig. It was first released in January 2006.

As we all know, the library has some predefined functions that we can use directly in our programming. We just need to include that library in which the function is defined.

Here is the same thing. It includes predefined functions. For example, for animation, it has function ‘.animate()’. One doesn’t need to write lines of code (CSS) for animation.

One of the drawbacks of jQuery is it has very complex syntax. One needs to have an inordinate practice of jQuery to remember the syntax.


It is an open-source javascript library to build the user interface. It is the component-based library. It is created by Facebook.

It creates virtual DOM in memory. First, it does all the necessary manipulation in virtual DOM before doing in the browser’s DOM.

It is used for the view layer of web/mobile applications. It corresponds to ‘view’ in the MVC application design model.


It is an open-source javascript framework for dynamic web applications. It is the superset of javascript. It allows extending HTML’s syntax to express application clearly.

It reduces the amount of javascript needed to make a web application. It enables to create reactive Single Page Applications (SPAs).

This framework is regularly updated by the angular team of Google.


There is much more when it comes to front-end development. Like Node.js (javascript runtime), VBScript, Express.js, etc.

To recapitulate, there are several languages and frameworks for front-end development. The selection of language and framework depends on the needs have in an application and as per the convenience of the developer.
