Working with Third-Party Libraries — quiz

A QA engineer installs `faker` for generating test data. TypeScript shows `Could not find a declaration file for module 'faker'`. What is the first thing to check?

• Uninstall and reinstall `faker` — the installation was likely corrupt
• Check if `@types/faker` exists on npm (`npm install --save-dev @types/faker`). If no `@types` package exists, the library either bundles its own types or requires a custom declaration file
• Add `"allowJs": true` to tsconfig to allow importing untyped modules
• Suppress the error with `// @ts-ignore` above every import
