Jest is a delightful JavaScript testing framework with a focus on simplicity and efficiency. It is widely used for testing JavaScript code, including React applications, Node.js projects, and more. Jest provides a zero-configuration setup, making it easy to get started with testing right away. It offers features like snapshot testing, mocking, and code coverage analysis, ensuring robust and reliable test suites.

Compared to other testing frameworks like Mocha or Jasmine, Jest stands out for its fast and parallel test execution, built-in matchers for assertions, and seamless integration with popular tools like Babel and webpack. Jest is actively maintained by the open-source community and is continuously updated with new features and improvements.
