# vitest/prefer-strict-equal 📝 Enforce strict equal over equal. ⚠️ This rule _warns_ in the 🌐 `all` config. 💡 This rule is manually fixable by [editor suggestions](https://eslint.org/docs/latest/use/core-concepts#rule-suggestions). ```ts // bad expect(something).toEqual(somethingElse) // good expect(something).toStrictEqual(somethingElse) ```
