Below are the most common programming languages for developing the front end. Front-end developers are usually part of an IT, product or software development team within a company.

Also, with the JQuery plugins in Bootstrap, you can build and deliver interactive solutions for modal popups, image carousels, and transitions. Keep up with the latest web development trends, frameworks, and languages. They allow multiple users to work on the same project without conflicting versions.

Preprocessors are another tool that front end developers can use to speed up CSS coding. A CSS preprocessor adds extra functionality to CSS to make your CSS more scalable and easier to work with. In practice what this means is that you can do fancy programming language type things like use variables and do simple math, stuff that normal CSS can’t do. The other, less obvious to the layman, use for version control is when you’re working on a team.

Front-end developers and UI/UX designers both work with the front end of a website or app. The user interface (UI)/user experience (UX) designer comes in at the beginning of the project.

Then, they create the layout for each individual page or screen using wireframe diagrams.

what should a front end developer know

Back-end developers, who operate and maintain the “behind the scenes” infrastructure of a website, such as servers and databases, complement front-end developers’ work. However, front-end web development is not restricted to HTML, CSS, or JS; there are a variety of alternative technologies to consider. Just remember – don’t compare yourself or your learning pace to that of others as you learn. Set aside some time each week or day to learn, do your best to stick to it, and then rejoice.


The reason we advise two options comes out of the specific of front-end developer job. It is unlikely that a freelancing specialist would possess such a high level of technical specialization in such a narrow field. On the other hand, you don’t want a business partner spending all his spare time coding instead of solving business problems. It is a program that lets you generate CSS from the preprocessor’s unique syntax.

So, if your business truly needs one (and you don’t want to waste money) you’d better understand the purpose of this role in a team, its power sides, and responsibilities. There are three types of preprocessors available – SASS, LESS, and STYLUS in which SASS and LESS are the most in-demand ones. It turns any stylesheet into a program and helps in creating small reusable components and extract libraries. SASS (Syntactically awesome style sheets) is an extension of CSS that enables you to use things like variables, nested rules, inline imports, and more. LESS (Leaner Style Sheets) is a backward-compatible language extension for CSS and it also enables customizable, manageable, and reusable style sheets for websites.

Stories to Help You Grow as a Software Developer

One of the first things to learn when learning JavaScript for web browsers should be DOM manipulation. It represents the structure and the content of any web document which also include styles and HTML part. To manipulate an element inside the DOM, the first thing you need to do is to select it and store a reference to it inside a variable. Without refreshing a page, you can update the data and change the layout of the page, and create customizable applications. For advanced level employees, there are other frameworks and learning TypeScript could be the next step. From the station “Progressive Web Apps,” you’ll find skills that you need to become a senior developer or to specialize in mobile app development, for example.

  • We highlighted the technologies we often encountered in job advertisements among employers’ expectations.
  • My belief is that due to the slightly shorter learning path to becoming a front-end dev, the majority of entry-level programmers go that route.
  • One thing that all front end developers must have, regardless of the job description or official title, it’s excellent problem-solving skills.
  • Bootstrap is a free collection of reusable pieces of code written in HTML, CSS, and (optionally) JavaScript.
  • Because of the differing distribution of frontend developer skills, the salary they can earn varies depending on where you work in the world.

Front-end developers will need to obtain applicable front-end or web development skills through an internship, on-the-job training and/or work experience. Knowledge in the areas of programming languages (CSS, HTML, JavaScript), UI/UX design, cloud computing platforms and effective communication are also recommended. When it comes to web development, it’s essential that frontend developers are aware of that and know the basics of responsive design. When designing a website, you need to make sure that its pages will adjust themselves to the device of your users. A front-end developer works on a website’s and application’s user interface.
