How to become a front end developer – Skills to have

Whereas website design deals with how a website looks, front end development is concerned with how the web design is implemented on the web.

Are you curious what makes a site act the way it does? Have you ever wondered upon arriving on a website how to become a front end developer?

Front end vs back end developer Jobs

What is a front end developer? A front end web developer creates websites using web design apps and JavaScript, CSS, and HTML to write codes that run inside the users’ browser. On the other hand, backend developers write codes that run on the webserver.

The back end developer will be the engineer responsible for designing systems such as water and sewer and electricity, all of which work together to make the city function.

The front end developer will be responsible for the actual layout of the streets and all the necessary connections inside the city that make it possible for people to live their lives.

A frontend developer will make sure that the website’s design renders well across all browsers and platforms and ensure an error- and bug-free front-end.

HTML & CSS: The Building Blocks of Web Design and Front-end Development

Are interested in how to become a front end developer? Do front end web developer jobs attract you? Or do you want to create your own IoT development company? The concepts of web design and front end web development wouldn’t exist without the standard markup languages for creating web pages and apps: CSS and HTML.

HyperText Markup Language, or HTML, and Cascading Style Sheets, or CSS, are the elementary blocks of creating a website design, from formatted text to adding images.

Any front end developer job description will include in-depth coding knowledge using HTML and CSS. Before searching for front end technologies, front-end web developer jobs, or web developer courses, you must focus on becoming a master of coding with CSS and HTML. You can also use services such as IT Recruiting for such options.

Once you gained HTML and CSS knowledge that is solid enough to work with, you are enabled to start building basic sites. Acquiring a working knowledge of CSS and HTML coding will not take years, but merely weeks if you concentrate on your goal and pursue it keenly.

JavaScript: The Most Popular Programming Language

In addition to HTML and CSS, JavaScript is a programming language that lets front-end web development specialists add functionality to the websites they create. JavaScript developers can make sites interactive via elements such as real-time updating maps, films, and games.

JS also allows for front-end developers to create basic applications and easy-to-use interfaces. For example, a page does not need to reload every time you pin something on a site such as Pinterest and that’s only due to the amazing capacities of Java Script. Learning JavaScript is a crucial step if you want to know how to become a front-end developer or pursue other web dev careers, including web programming or web design. Nowadays, JavaScript is highly used and has become a super famous programming language.


There are many JavaScript libraries, but jQuery is the most popular. A multifaceted, versatile JS library, jQuery is a set of extensions and plugins that enhance web developing using JavaScript. It consists of prêt-à-porter elements to avoid writing code from the ground up.

A frontend web developer and any other web developer can easily adapt these ready-made elements as per their specific needs, which is why learning JavaScript is key if you are looking to learn how to become a front end developer or front end design specialist.

There are plenty of ways that you can use jQuery, including automatic resizing and rearrangement of grid layouts, countdown timers, or search form autocomplete.

JavaScript Frameworks

There are numerous JavaScript frameworks available, including Ember, Angular, React, and Backbone, just to name a few. Understanding frameworks and knowing how to work with them will accelerate development, including front-end web development, substantially.

Although the virtual world is packed with many JS frameworks designed to meet specific needs, you can consider the above-mentioned 4 JS frameworks as the most widely used. In job listings, employers look for a front end developer that knows these specific frameworks.

CSS and Front End Frameworks

There is also the concept of front-end frameworks that are to CSS what JavaScript frameworks are to javaScript: they offer a jumpstart to speed up the coding process. The most popular front-end framework is Bootstrap although there are many more out there.

Most CSS projects commence with the same elements, which is why developers need a framework that offers these pre-written elements saving them a lot of time. If you want to know how to become a front end developer, start looking for ways to learn CSS frameworks.

Experience with CSS Preprocessors

What is front end development if not front end programming and front end web design? What are the best front end developer skills? Perhaps the ability to speed up the development process is the skill that you should be focusing on as an upcoming developer.

Within this context, knowing how to use and work with CSS preprocessors is essential because they are elements designed to allow for faster and easier CSS coding. Preprocessors make working with CSS a straightforward activity by making CSS scalable and functional.

Preprocessors, as the name correctly suggests, process codes before publishing. They subsequently format your CSS code, and make it friendly across all browsers. The most popular preprocessors that employers expect you to know as a developer include LESS and SASS.

Experience with RESTful Services and APIs

Representational State Transfer, or REST, is an easy-to-use architecture that defines a set of HTTP-based constraints and properties. REST streamlines network communication on the web. Web services that follow the REST architectural style include APIs and RESTful.

In a hypothetical scenario where you would want to design an application that will display social media connections in the order in which you connected, you could call on RESTFUL APIs of Twitter or Facebook to read your list of connections and return the results to you.

Using REST lets you call on any web service that uses RESTful APIs. Despite the apparently overwhelming technicalities, Restful Services and APIs enhance communication with web services, increasing their performance, scaling, reliability, changeability, and movability.

Front-End Build Tools

In the process of learning how to become a front end developer, you will often hear about front-end build tools and how knowing how to use these frontend build tools is one of the essential front end developer skills. Front-end build tools are very helpful for developers.

Frontend build tools allow developers to manage workflow and file size optimization in an efficient manner. Here are some examples of how you could use front end build tools:

  • Package managers such as Bower can help developers keep their assets, libraries, and other elements across large or team projects sorted out and well-organized.
  • A frontend build tool such as can help developers get started rapidly with projects and remain productive. is run on the command line.
  • Gulp or Grunt are two frontend build tools that developers use as task runners to optimize workflow and compress files. These tools have many plugins, run on the command line and are compilers for preprocessors such as SASS or LESS.

Essential Frameworks to Know

Based on JavaScript, HTML, and CSS languages, Bootstrap is an open-source framework used to develop websites. It is coined as the most frequently employed framework that specialists adopt for the development of mobile-first, responsive design web projects.

Bootstrap makes page layout more accessible. Streamlined CSS and added functionality are inbuilt and a developer is only required to add structure and classes to HTML elements.

You can use specially designed tools that enhance Bootstrap-based web development, including Visual Studio with its IntelliSense that allows for code snippets and autocompletion of classes. Creating a multifaceted web structure is a couple of clicks away.

Another open-source framework, Ember uses the Model-View-View-Model development pattern to create bold web projects. Ember is a set of different pieces designed to help and simplify the development of SPA, Single Page Application. The concept used by Ember:

  1. Routing refers to pages in your web project and how to get to those pages
  2. Templates organize the HTML layout using Handlebars, i.e., a set of double curly braces enclosing properties to be displayed: {{fullName}}.
  3. Models hold data for your web project, including every detail of every piece of info that developers use in the pages of their web project.
  4. Components control how the user interface behaves in your web application. They employ template files to define the behaviour of the UI element on the page.
  5. Services are employed for persisting data for the user’s session in your web app

FAQ on becoming a front-end developer
