Web site layout and web programming attract a large number of newcomers to the IT world. This is due to a fairly low entry threshold. The number of those who want to become a frontend developer is increasing every year, as a consequence, the requirements to the candidates are also growing.
Let's figure out what technologies you need to learn to become a Frontend developer.
HTML and CSS are the core technologies that every web developer uses. The markup of each web page is created using the HTML hypertext markup language. The CSS style language makes a site beautiful and gives it unique styles. In addition, you must have:
Pay special attention to the layout for mobile devices, today most people use the Internet through a smartphone. There is even a special layout approach when the site is first designed for mobile devices, and only then for desktops, this approach is called Mobile First.
These are the general requirements for the layout. Now consider in more detail the requirements specifically for the CSS style language. Here you should know the basic properties of CSS: gradients, backgrounds, transitions, animations, transformations, shadows as well as the Flex and Grid technologies, which we will talk about later.
A good knowledge of HTML and CSS will be enough to create a website layout and earn money from it. It is with these two fundamental technologies that the path to the profession of Frontend developer begins.
Technologies for the layout of reliable adaptive web pages that make it easier to create dynamic sites and more convenient to structure their content.
Popular HTML/CSS platform for developing adaptive web applications, which is used to create websites and admin panel interfaces. The main advantages of Bootstrap:
Also, it will be useful to know two more CSS frameworks: Foundation and Materialize. The first is a comprehensive and professional tool that follows the principle of Mobile First. It has an advanced interface and allows you to create really unique, elegant and easily customizable websites. Under the aegis of the Foundation, web services such as Facebook, Mozilla, Adobe, Amazon, eBay and many others were created.
Materialize professes the principles of Material Design from Google, which pursues the idea of digital unification for an easier and more comfortable interface experience.
A CSS preprocessor is a program that has its own syntax, but can generate CSS code from it. The most popular are SASS, Stylus, LESS and PostCSS, but SASS has the largest community. The preprocessors are designed to:
Learning just one preprocessor will be sufficient to increase the efficiency of CSS code writing.
Git - the most popular system of version control, which allows you to keep a history of the project development with the ability to access each saved version.
In addition, it is worth knowing how to work with online hosting service for projects that use a version control system. In this case, it's GitHub. In tandem with Git, it allows developers to save their code online, and then interact with other developers in different projects.
These systems allow a team of programmers to work on one project at a time, saving changes made, and track the performance of each team member.
Git & GitHub are very important tools for any IT developer and should be learned as early as possible.
Knowledge of web technologies and the Internet
To do his job well, a frontend developer must understand the web and understand how it works. Thus, it is necessary to know:
Also, it's a good idea if you try to set up a site on some free hosting, link the domain to that hosting.
This mechanism is useful for a single developer (for self-monitoring), and for a team effort when each developer must follow the same language constructs to come up with a unified, coherent project.
Jest, Cypress and Enzyme - the main tools of unit testing, which falls on the shoulders of the developer. But what is it?
Unit testing (aka unit testing) is a process which consists of creating tests to make sure that the individual sections of the code written by the developer work properly. This is performed directly by the author of the code.
You don't need to learn all three tools - it's enough to learn how to handle just one of them.
Understanding of algorithms and data structures is a must for any programmer.
Data structures include: stacks, queues, linked lists, graphs, etc. By learning them, you will be able to manage the complexity of your programs, making them more understandable, as well as develop high-performance programs that work efficiently with memory.
Knowing algorithms will allow you to create complex designs to solve a wide range of problems efficiently. When they talk about algorithms, they usually mean algorithms for sorting and searching: sorting by direct inclusion, direct selection, merge, pyramidal, direct search, binary, index-sequential, and others.
It is also important to understand the Big O notation, which describes the complexity of each algorithm. This mechanism helps to determine under what conditions it is more profitable to use a particular algorithm.
Note that as a beginner, you do not need to dive deep into these topics. It will be enough a theoretical knowledge, as well as the ability to write a few algorithms. In website development it is not much needed, but practically no interview is avoiding the topic of templates, algorithms and data structures.
The frontend developer is a pretty versatile fighter in the world of development. He should be able to do a good layout and create the logic of the client side, and understand the work of the server side of the web application. To master such a large set of necessary tools, it is worth spending time, patience and perseverance.
The means of website development listed in the article also have analogues, because different web tools are suitable for different tasks. However, we have chosen the most popular and effective of them.
