This package provides TypeScript definitions for Jest, a popular JavaScript testing framework. Using @types/jest enables type checking and autocompletion when writing Jest tests in TypeScript projects. It includes definitions for Jest's core APIs like describe, it, expect, and matchers, improving code quality and developer experience. By installing this package, TypeScript developers can leverage static typing to catch errors early and ensure their tests are robust and reliable. Keeping it updated with the Jest version is crucial for compatibility.
