Why Should You Read This Article?
Understanding and mastering Front-End terminology will not only help you become a skilled web developer but also give you a deeper insight into how web technologies work and how to optimize your website.
This article will provide an overview of the most common terms in this field and explain why they are important for Front-End Development.
Common Terms
Code Split
Code splitting is the process of dividing your application into smaller chunks that can be downloaded more efficiently, helping to speed up page loading times and improve the user experience.
Lazy Load
Lazy load is a technique that delays the loading of a resource until it is actually needed. As discussed in the previous video, loading images before the user needs to view them leads to wasted resources.
By implementing lazy load, images are only loaded when the user is near the image’s location on the webpage. This not only helps save the user’s computer resources but also reduces the strain on their internet connection.
In this context, “resource” can be defined as anything from a source code file, an image tag, a library, to a response from an API. When applying lazy load, you need to carefully consider which resources can be deferred for loading and which cannot.
Prefetch/Preload
Prefetch and Preload are directives used by the browser to load resources necessary for the next page in advance, improving response times and user experience.
Tree Shaking
Tree Shaking is the process of eliminating unused code from JavaScript bundles, helping to reduce file size and improve page loading speed.
SEO (Search Engine Optimization)
SEO refers to optimizing your work to enhance the visibility of your website on search engines, ensuring that your content is found and highly ranked by users.
Google Page Speed
Google Page Speed is a tool for evaluating the loading speed of a website, offering suggestions and recommendations for improving the site’s performance.
The Fold
The Fold refers to the portion of a webpage that users can see without scrolling. It is a crucial area to place important content and make a strong first impression on users.
CSS Critical
CSS Critical involves loading the CSS required to render the top portion of a webpage quickly, improving load times and user experience.
CSS in JS
CSS in JS is a method of using JavaScript to generate CSS for web applications, enhancing code reusability and management.
Service Worker
A Service Worker is a special type of script that runs in the background of the browser, improving performance and enabling offline functionality for web applications.
Web Worker
A Web Worker is a type of JavaScript object that runs in a separate background thread, helping to handle complex tasks without slowing down the user experience.
