The main difference between .ts and .tsx file extensions lies in the use of JSX syntax.
.ts files are for standard TypeScript code, while .tsx files are for TypeScript with JSX syntax.
.tsx files are commonly used for React components that involve JSX rendering.
.ts files contain pure TypeScript code, whereas .tsx files have TypeScript code with embedded JSX elements.
.ts files are compiled to .js files, while .tsx files are compiled to .jsx files after JSX transformation.
In React projects, .tsx files are essential for React component files.
.ts files use standard TypeScript syntax only, while .tsx files use TypeScript syntax along with JSX syntax.
.tsx files are crucial for passing interfaces to components and using custom hooks in React.
Best practices for React development using TypeScript include utilizing linters, utilities, generics, and enhancing project structure.
Overall, .ts and .tsx file extensions serve different purposes in TypeScript-based projects, with .tsx files being critical for React components and JSX integration.
