10 Topics you must know if you want to be a web developer - a beginners guide

Whiles web development is on the rise most people either learn it for career purposes or for other reasons. The career path for web developers is quite uncertain because it doesn't matter what stack or roadmap you choose to follow. Some choose to start with the basics whiles others just apply their previous knowledge.

In this article, I will list 10 Topics you must know if you want to be a web developer as a beginner or an advanced developer. These lists are categories of Fronted, Back-end, Web architecture, and some advanced techniques.


10 Topics you must know if you want to be a web developer - a beginners guide

  1. HTML 



HTML is a popular markup language in the domain of web development. HTML codes are rendered by browsers which makes it the language for all web browsers.

The majority of web pages are written in HTML which makes it a core topic you must know if you want to develop powerful web pages. 

  1. CSS  


Cascading Style Sheet is referred to as CSS. As a web developer you need to know about CSS, from its fundamentals to more complex ideas, and covers all released versions 1, 2, and 3 of the language.

To develop a stunning, awesome, and good-looking website then CSS is the right technology to use. Most web developers do not invest much time to learn how CSS really works. 

  1. CSS Frameworks


The developer's task is greatly facilitated by this library of frequently used design patterns and codes. Ready-to-use classes contain all of these patterns and solutions to difficulties.

The major goal of CSS frameworks is to drastically cut down on the tiresome, repeated authoring of code fragments that are already being used on other projects. That is made possible by a variety of preset HTML and CSS components.

  1. JavaScript



Anyone can create a website with only HTML and CSS, but it won't accomplish anything lot. JavaScript adds functionality, which gives the webpage life. It is in charge of user-interactive features including drop-down menus, modal windows, and contact forms. Additionally, it is used to make interactive maps, video players, and animations.

But is JavaScript worth learning? 96.5% of websites use JavaScript today, and despite being created as a client-side language, it has now found its way to the server side of websites (thanks to Node.js), mobile devices (thanks to React Native and Ionic), and desktop computers.

Even more, power is added by package managers like npm. An interactive website gains more retention from both users and web visitors. 

  1. Web Forms


With web forms, you can simply and effectively gather and manage information using web forms. Because they are already integrated into your website, sharing their information is simple for your leads. When a lead fills out a form on your website, the data is saved until it can be analyzed.

  1. JS DOM, Events, and Objects



The whole HTML document is interpreted as an object by the Document Object Model or DOM. The document object has attributes that may be changed using specific methods, much like any other programming object.

In the same way, all items included within the document object are referred to as nodes in the DOM and have attributes that may be handled using JavaScript methods.

  1. JS Functions and Arrays



With the function keyword, the function name, and the list of parameters in parenthesis, functions may be declared in JavaScript (without a var declaration). Curly brackets surround the actual definition of the function. When using the return keyword, you may either end the function or return a value.

"new Array()," is an example of a JavaScript array that returns an empty array, "new Array(size)," which returns an empty array of a certain size, "[ ]" for an empty array, or "[a,b,c]" for an array filled values.

  1. Asynchronous JS and Fetch API




You now have access to a plethora of APIs, including free datasets and the ability to trigger features in your preferred products.

Your horizons may truly expand if you have a solid understanding of asynchronous javascript and dealing with APIs in general.

  1. ReactJS


React isolates and takes the DOM away from you, which results in a simpler development architecture and improved website or web app performance. React can also power native apps using React Native and Node, and it can render on the server.

Larger programs are easier to manage because component and data patterns enhance readability.

  1. Web Application Architecture



Applications, databases, and middle-ware systems communicate with one another on the web according to the web application architecture. The simultaneous operation of several apps is ensured. An easy example is just when you visit a webpage.

When a user types a URL into a web browser's address bar and clicks the go button, that specific web address is requested. Files are sent to the browser by the server in response to a request. The requested page is then displayed by the browser by running those files.

User interaction with the website is finally possible. The web browser's code parsing is the most crucial point to keep in mind in this situation. The operation of a web app is comparable.


When it comes to learning is a continuum process that needs a huge amount of time and dedication. There are tons of topics for a web developer but these are the most relevant ones that need to be studied and apply. We hope this piece helps channel you to the direct path.
