Web development is a highly sought-after skill, making it an attractive career choice. It is one of the most accessible and highest paid courses. To be a successful developer, you must have a thorough understanding of the HTTP and HTTPS web protocols and how they work, as well as how clients and servers communicate. Knowledge of the Secure Shell Protocol (SSL), which is used to encrypt data between servers and clients, is also very beneficial.
JavaScript can be used both as client-side and server-side technology. It can be used to add interactivity to web pages, improve browser security, manage web content dynamically, and more. It is also compatible with numerous libraries and frameworks that make life easier for a web developer. Web developers often need the command line to install packages and create web applications.
Many web technologies are based on APIs and it is important for developers to know the underlying protocols in order to use those technologies efficiently. Regardless of the tool, framework or library you use, HTML and CSS are essential (HTML5 and CSS3 are the latest standards that work in the most common browsers on the market). HTML (HyperText Markup Language) is the standard markup language for creating websites, and HTML documents consist of elements that are represented by tags. I don't know how many HTML tags there are, but to start with, you should take a look at the 10 best HTML tags.
Many HTML tags can contain additional information in the form of attributes. Mastering HTML is key to becoming a great web developer. As mentioned before, CSS (Cascading Style Sheet) is essential in web development. We use it to add style to our website, including layout and design.
We also use it to properly display our website on different devices and screen sizes. On the one hand, we talk about elements in HTML, but on the other hand, we talk about how these elements should be displayed in CSS. The central part of the CSS are its properties. It's hard to say how many properties exist because the list is continuously updated. One of the best parts of CSS is that it saves you a lot of time.
Not only by correctly using the CSS selectors, but also the CSS selector classes, you can manage the style of multiple pages. JS (JavaScript) is a high-level computer language. There are other high-level languages that can be used in web development, such as PHP or Python, but when we talk about the World Wide Web, along with HTML and CSS, there is always JavaScript. Debugging is a process in which you find errors or any type of abnormality in your code, and then correct or change it. On average, a software developer spends no less than 33% of their time debugging.
This is a very complicated and slow process, but unfortunately, it is a necessary evil. Over time, debugging becomes fun because it's like solving puzzles and a small fix can make everything work. Fortunately, all modern web browsers have debugging tools, and if you code in JavaScript, this process is simplified. Debugging tools allow you to see the inner workings of a JavaScript web page while it is running. This is where tools like GIT come into play.
To some extent but still incredibly useful, code version control tools allow you to make mistakes without consequences. I don't know where you come from but knowing graphic design is a great advantage. In addition, if you are not familiar with graphic design, you should familiarize yourself with some of the tools that graphic designers use. This is important because at some point along the way to becoming a web developer, you'll be given a design that you'll have to bring to life on the web. To make things easier for you, below is a list of graphic tools. If you learn the basics of at least three tools listed below it should be enough.
As a backend web developer, you must also learn to create JavaScript applications outside the browser using popular platforms such as Node JS. This helps you create a more dynamic web page since you'll be working with JS; it's also important to learn how to create a JSON file (JavaScript object notation) that is used for communications between the browser and server; if one day an application such as a mobile application needs the same data that you have in your database then you'll have to learn how to create an API (Application Programming Interface).Web hosting allows you to store your resources (HTML files, CSS files, JS files, images databases) on a server that has excellent Internet connectivity and can be accessed via the World Wide Web. As you program you'll learn that at some point parts of your code can be used in almost completely different projects; for example in JavaScript there are several commonly used functions so why write them from scratch every time? This is where we use libraries. In JavaScript libraries contain finished functions that an application can use to perform a task and facilitate programming; in CSS we can use libraries that already have commonly used classes. While roles of web developers and designers are interdependent they are also very different in terms of their skills and required functions; web developers must be able to realize customers' vision by developing websites that work well and are implemented with new features and updates. A good web developer must have some exposure to DBMS (database management system) that allows them to effectively manage data; they must ensure design adapts to changing screen sizes whether it's desktop computer tablet or smartphone; nowadays specializations in front-end and back-end development are most preferred by web developers; Hertfordshire-based companies need experienced digital professionals so this is ideal time to consider career change.
