This package contains TypeScript definitions for Expect, a core assertion library often used with testing frameworks like Jest. By installing this type definition, you gain autocompletion and type checking when writing tests in TypeScript, ensuring that your assertions are correctly formed and compatible with the values being tested. Leveraging @types/expect enhances code quality and reduces runtime errors in your test suites. Its primary function is to provide a seamless TypeScript integration with Expect's assertion capabilities.
