React Native Performance Javascript vs Typescript

Question

Is Javascript or Typescript different in React Native App performance?

Which Javascript or Typescript is recommended for developing React Native application?

Answer 1

TypeScript is just compiled to JavaScript. Think of TypeScript as a tool like ESlint that helps you write better code, just in a different way (forcing object types, etc). There will be no performance change to the user, only difference is in whatever step you do to build your application will now have to have a TypeScript parser that compiles it.

Answer 2

The performance of React Native with JavaScript and TypeScript is very similar. There are some performance differences, but they are minimal. JavaScript is generally considered faster than TypeScript, as it does not need to be compiled. However, TypeScript has several features that can help optimize the performance of React Native apps, such as static typing, which can help catch errors at compile time instead of at runtime. Ultimately, the choice between JavaScript and TypeScript will come down to the developer’s preferences and the specific requirements of the project
