How to write React components in TypeScript (2022)
For new components, it does make sense to follow the style defined in the React documentation by writing components using a function definition. However, arrow functions using React.FC also remain a popular choice and are used by Vercel and the official TypeScript website

Where do you guys keep your types
Yep, this is my answer too - I use this pattern pretty often. For example, here's the main object that represents the TypeScript Playground at runtime: https://github.com/microsoft/TypeScript-website/blob/86901a0520855050b16b0c23bd6923212fdd0c9c/packages/playground/src/index.ts#L622-L623

Creating a modern JS library: Writing good code
Beyond testing your code, it's an excellent idea to write your library in TypeScript. Type errors are among the most common type of mistake in JavaScript, so using TypeScript will almost always reduce development time and may occasionally prevent you from publishing broken code if you forget to add a test. Moreover, the excellent TypeScript compiler will allow you to avoid using a bundler when publishing your package (we'll get into this more later) and will make supporting TypeScript and JavaScript users simultaneously much easier.

Unit Testing Expo Apps With Jest
console.error Jest encountered an unexpected token Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax. Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration. By default "node\_modules" folder is ignored by transformers. Here's what you can do: • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it. • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript • To have some of your "node\_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config. • If you need a custom transformation specify a "transform" option in your config. • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option. You'll find more details and examples of these config options in the docs: https://jestjs.io/docs/configuration For information about custom transformations, see: https://jestjs.io/docs/code-transformation
