Setting Up TypeScript in an Existing JS Project — quiz

After running `npm install --save-dev typescript` in an existing JavaScript Playwright project, what is the minimum next step before TypeScript can compile any files?

• Rename all .js files to .ts immediately
• Create a `tsconfig.json` — TypeScript needs a configuration file to know what to compile, which target to emit, and what settings to apply. `tsc --init` generates a starter config
• Install `@types/node` as the next dependency
• Add a `"scripts": { "tsc": "tsc" }` entry to package.json
