what is TypeScript? with example

C# Corner Support · Answer

TypeScript is a programming language developed by Microsoft that builds on JavaScript by adding static type definitions. It aims to make JavaScript development more robust and scalable. In TypeScript you can explicitly define the types of variables function parameters and return types which helps catch errors during development and improves code maintainability. Here's a simple example to illustrate TypeScript's static typing: // Define a function with typed parameters and return type function greet(name: string): string { return `Hello ${name}!`; } // Call the function with a string argument const greeting: string = greet(TypeScript); console.log(greeting); // Output: Hello TypeScript! In this example the `name` parameter is explicitly typed as a string and the function's return type is also defined as a string. This ensures that the function is used correctly with the appropriate types of data. Let me know if you would like to explore more about TypeScript!
