If we want to create a named event handler function, we must hover over the event handler prop to learn what the function parameter type should be. This saves a lot of effort and makes it easier for a new developer to use your source code. You can download CRA as a npm package using the npx command. What does this all do?
It renders checks on our code. Readability and validation: Since Typescript is a statically-typed system, you can add types to variables, functions, and properties, making your code far easier to read.

Note: in React, function components are functions that take in a props parameter to return JSX. Remove previously installed versions with npm uninstall -g create-react … It’s basically a more powerful replacement for prop-types, since it supports more advanced types and can type normal JS code, too.
