Jest is a JavaScript testing framework that allows for unit testing JavaScript code. It provides features like mocking functions, testing asynchronous code with promises and async/await, and snapshot testing. Jest can integrate with other tools like Webpack and Enzyme and provides advanced features like testing multiple projects at once and built-in code coverage.
