Front end (or F/E) development, or user interface development, is a branch of web development. The role of a front end developer involves creating and managing the user interface (UI) of the website. Since almost every business is trying to have an online presence for their customers, front end developers are heavily in demand. This is why a course on front end development is a frequent part of sessions for placement training for engineering students. A ton of programmers specialize in front end work because they like to focus on the user environment and experience.
- HTML
HTML is the most basic of all front end developer skills. It is a markup language that allows you to define and format text on a web page. HTML also allows you to build interactive forms, tables, and links to other pages. If you want to build any web application, then you need to learn HTML.
- Cascading Style Sheets
CSS is used to style web pages by defining their appearance and layout using selectors, properties and values. It is used for styling websites, apps, and other interfaces but can be used for many other purposes as well. CSS is much more powerful than just changing the colour or font size of an element; it can be used for positioning elements on the page, creating animations or even building entire websites from scratch without any code!
- JavaScript
JavaScript is probably one of the most important skills when it comes to front end development because it helps us add interactivity to our web applications by making them dynamic rather than static pages like HTML does. JavaScript can be used to add functionality like tabs on your website or add some extra info when someone clicks on an image (like Google Maps).
- DOM Manipulation
DOM manipulation is the process of changing the structure and appearance of a web page using the Document Object Model (DOM). It involves adding, removing, and modifying elements within an HTML document. This is one of the most important front end developer skills you need to know as it allows you to make changes to a live website.
- AJAX
AJAX Asynchronous JavaScript and XML communicate information between the client-side and server-side in an asynchronous fashion without requiring reloading the page, meaning that it doesn’t wait for the server’s response before continuing with the rest of its processing. It’s often used for simple tasks such as updating sections of a webpage when something in another section changes but can be used for far more complex tasks as well.
- jQuery
jQuery is a JavaScript library that makes coding easier by simplifying common tasks like event handling, animation, and Ajax updates. It helps developers avoid repetitive tasks such as typing out long lines of code or creating multiple functions for different tasks. The jQuery library can be used for almost any task imaginable on a website including creating simple menus, manipulating DOM elements, making AJAX requests, animating elements on the page and more.
- JSON
JSON is a data format known as JavaScript Object Notation. It’s used in passing data between web servers and browsers, and it’s also used to pass data between different applications. It’s important because it’s the standard for sending data back and forth in APIs. There are other ways of doing this, but JSON is the most common (and the easiest to use). This is why no front end developer certification course is complete without a lecture on JSON.
If you’re going to do any kind of front end development work, you need to know about JSON.
