Why use TypeScript? What are the key advantages of TypeScript?

TypeScript is used to add static typing to JavaScript, which brings several key advantages:

• Early error detection: type errors are identified at compile time, reducing the number of bugs at runtime.
• Improved code readability and maintainability: types serve as documentation, making it easier to understand data structures and function contracts.
• Support for modern language features: TypeScript supports new ECMAScript standards and additional features such as interfaces, enums, and generics.
• IDE integration: autocomplete, refactoring, and code navigation work better thanks to type information.
• Ease of scaling projects: in large teams and projects, typing helps avoid errors during changes and improves collaboration.

Example of using TypeScript:

interface User {
  id: number;
  name: string;
}

function getUserName(user: User): string {
  return user.name;
}

const user = { id: 1, name: "Ivan" };
console.log(getUserName(user));

Here, types help ensure that the function receives a correct object and returns a string.
