tslint-no-unused-expression-chai prevents accidental unused expression errors when using Chai's expect assertions within TypeScript projects using TSLint (now superseded by ESLint). This linter rule specifically addresses the common false positive TSLint generates when chaining Chai matchers. By adding this rule, developers avoid unnecessary // tslint:disable:no-unused-expression comments, ensuring cleaner and more maintainable test code while leveraging Chai's expressive assertion syntax.
