Introduction to TypeScript for JavaScript Developers

TypeScript adds static typing to JavaScript, helping you catch errors early and write more maintainable code. ## Why TypeScript? TypeScript provides type safety, better IDE support, and improved code documentation. It's especially valuable for large codebases and team projects. ## Basic Types TypeScript includes primitive types like string, number, boolean, as well as complex types like arrays, objects, and custom interfaces. ## Interfaces and Types Define the shape of your data using interfaces and type aliases. This makes your code more predictable and easier to understand. ## Generics Generics allow you to write reusable, type-safe code that works with multiple types while maintaining type information. ## Migration Strategy You can gradually adopt TypeScript in existing JavaScript projects. Start by renaming .js files to .ts and adding types incrementally.
