With the ever-expanding functionality of web applications, user expectations have also increased manifold, and therefore for higher user retention new features get added to web applications every few weeks.

To test these features to ensure that the application UI is working well, and provide a flawless experience to the end-users automation testing is essential. Automation testing has made it easier and more efficient to perform automated UI testing of applications. It is particularly useful when development cycles are short and the features have to be added every few weeks to keep up with the users’ demand.

JavaScript is one of the most widely used scripting languages when it comes to web automation. Whether you are a fresher or experienced in the domain of UI development and UX design you must have been familiar with JavaScript and CSS libraries. These libraries help developers simplify development tasks, improve performance, and add functionality to web applications.

In this article, we will discuss the best JavaScript and CSS libraries that can be utilized to build the next project in 2024 and make the lives of web developers much easier. We will first understand what JavaScript and CSS libraries are, and then we will see the best library for 2024.

Both CSS and JavaScript are used on Web pages with HTML but for different purposes. To design the webpage for better layouts for the user, CSS is used so that the users have a seamless experience with the Web page. JavaScript, on the other hand, is used to create interaction between web pages for the user. Let’s have a brief understanding of each of them separately.

JavaScript

For creating web automation test scripts, JavaScript is one of the most widely utilized programming languages among testers and developers across the world. It is a lightweight, cross-platform, scripting language used by developers for developing web pages. JavaScript can be used for Client-side as well as Server-side developments.

One of the reasons for its popularity is that it provides a wide range of frameworks and libraries with multiple functionalities and features to make application and website development much easier. It is a versatile programming language containing a large number of frameworks, a standard library of objects like array, date, and time, and a core set of language elements like operators, control structures, and statements.

JavaScript allows developing and testing both the front end and the back end of an application.

What is a JavaScript framework?

JavaScript is a set of pre-written codes that simplify coding and enable better task performance on a webpage or JS-based application. JavaScript libraries contain various functions, methods, or objects to help extract specific functionality for the type of app developers build, and this makes the base of JavaScript frameworks. In short, it can be said that the framework regulates the app structure.

Developers can reuse the JavaScript codes to perform a certain task, like preparing a slideshow, instead of writing it from scratch. This saves developers their time and effort and brings simplicity to the entire development process. 

What is a CSS Framework?

CSS is the abbreviation used for Cascading Style Sheets. A CSS framework is a ready-to-use library of code that enables fast implementation and consistent website styling and layouts. It contains style sheet language that is used to shape the HTML elements to be displayed in the browsers as a web page. Without using CSS, the website which has been created by using HTML will not look appealing or satisfying. In short, CSS gives the outer cover on any HTML elements of the web page.

Its stylesheet collection makes the job of UI developers easier. CSS frameworks include pre-written, reusable code for common design elements and components to quickly create familiar and consistent user interfaces or website designs.

Benefits of using JavaScript and CSS Library 

Both JavaScript and CSS libraries and frameworks provide developers with a wide suite of functionalities and versatile and dynamic features to develop websites. These frameworks became popular because they provide the basis required to build applications in JavaScript.

  • JavaScript and CSS libraries help to minimize the time complexity by reducing lengthy scripts into libraries where they can be reused by function or adding a class.
  • Enabled developers add an enhanced functionality to guarantee a better user experience.
  • The web application performance gets enhanced since these libraries reduce CSS and JS files and guarantee smaller code sizes.
  • Using these libraries users can add effects like blurring, lightening, sharpening, saturation, hue, adjusting contrast, reflection, and many more to make the web page more interactive and engaging.
  • The other key benefit of using them is that all of the styles, UI elements, buttons, and more will appear consistent and out of the box. Developers don’t need to spend their time changing individual styles to ensure that they all have the same spacing and font sizes.

In short, they are widely used because they help developers ensure that the website looks and feels familiar to users.
