A simple guide for migrating from JavaScript to TypeScript
Blog post from LogRocket
TypeScript, a static type checker and superset of JavaScript, enables developers to detect type errors before runtime, offering a seamless transition from JavaScript projects without needing a complete restart. Migrating to TypeScript involves changing file extensions from .js to .ts and configuring a tsconfig.json file to manage compilation options and file inclusions. TypeScript's flexibility allows for incremental adoption, enabling coexistence with JavaScript files and integration with existing build tools. Developers should ensure their IDEs support TypeScript for an optimized development experience, while additional @types packages are necessary for frameworks like React to define type definitions. By creating specific types or interfaces for component props, developers can leverage TypeScript to enforce type safety and eliminate errors. Styled components can be enhanced by defining prop types, ensuring TypeScript understands custom styling logic. Overall, transitioning to TypeScript enhances code reliability and maintainability, allowing for gradual adoption across a project.
