How to create a TypeScript React app?

To create a TypeScript React app, you need to get familiar with the tools available under the hood. Not only is TypeScript a really great way to write JavaScript, but it also provides developers with runtime support to create a TypeScript React app. TypeScript is a superset of JavaScript and has been developed by Microsoft in collaboration with several companies such as Facebook, Google, and Twitter.
npx create-react-app my-app --template typescript
or
yarn create react-app my-app --template typescript

It provides developers with an option to program in a strongly-typed language that compiles to JavaScript at runtime so that JavaScript developers can use it without any change in their application.
