You can test applications such as user interfaces, frontend frameworks, react applications, architecture applications, utilities, regex applications, and so on using JavaScript testing libraries. 

JavaScript is an interpreted, lightweight, or just-in-time compiled programming language. Many non-browser environments, like Node.js, Apache CouchDB, and Adobe Acrobat, use it, although it is best known as the scripting language for Web pages. JavaScript is a prototype-based, multi-paradigm, single-threaded, dynamic language that supports object-oriented, imperative, and declarative (such as functional programming) programming styles. 

A web page or web application module is tested using JavaScript by writing test code specifically for it. It is then incorporated into HTML as an inline event handler and run in the browser to check that all functions operate as intended. Types of JavaScript testing: unit testing, integration testing, end-to-end testing (E2E), grouping tests.

JavaScript testing frameworks help us check the correctness of our code. They can also execute automated test cases on various browsers or mobile devices. A JavaScript testing framework called Jest is intended to ensure the accuracy of any JavaScript codebase. It enables you to create tests using an easy-to-use, well-known, feature-rich API that provides results promptly. Many other JavaScript frameworks are available, like MochaJS, Jasmine, Karma, NightwatchJS, etc., for JavaScript testing.
