Jest is a JavaScript testing framework that is often used for testing JavaScript applications, including React applications. The "jest" command is used in the command line interface (CLI) to run tests using Jest.

When you run the "jest" command, it looks for any files in your project that match the naming convention for test files, typically ending with ".test.js" or ".spec.js". Jest then executes these test files and reports the results.

Jest provides a wide range of built-in features for testing, including support for assertions, mocking, code coverage, and asynchronous testing. It also offers a convenient and easy-to-use API for writing test cases and assertions.

By running the "jest" command, you can initiate test execution and get visual feedback on the test results in the terminal. It will display information about the number of tests passed, failed, or skipped, along with any error messages or console logs generated during the test execution.
