Convert your JavaScript code to TypeScript.

run npx typesify in your project root directory.

To exclude files from being transformed use keyword --exclude followed by a comma separated list of glob patterns. For example to exclude all files in node_modules and dist directories: run npx typesify --exclude **/node_modules/**,**/dist/**

1. Typesify converts all .js and .jsx files in your project to .ts and .tsx files respectively.
2. Typesify adds a tsconfig.json file to your project root directory.
3. Typesify adds @ts-check to the top of all .ts and .tsx files.

Converting a project at work to typescript, I thought instead of using all of the great packages out there, I would build one myself! It is a good enough starting point to migrate a Javascript React project to Typescript.
