- What is TypeScript?
- TypeScript is like a helper for JavaScript. It helps you write better code by adding more information about what your code is supposed to do.
- Why do people use TypeScript?
- People use TypeScript to catch mistakes early. It adds a safety net to JavaScript, making it easier to understand and less prone to errors.
- Explain the difference between JavaScript and TypeScript.
- JavaScript is like the main language, and TypeScript is like an upgrade to it. TypeScript has extra features that help you write more reliable code.
- What are TypeScript types?
- Types are like labels for your data in TypeScript. They help you and others understand what kind of information your code is dealing with.
- What is a TypeScript interface?
- An interface is like a contract for your code. It defines what properties or methods an object should have, making sure your code works the way you expect.
- How does TypeScript help in catching errors?
- TypeScript looks at your code and warns you if something seems off. It helps you find and fix mistakes before you run your code.
- What is the “any” type in TypeScript?
- “any” is like a wildcard in TypeScript. It means you can use any type of data, but it doesn’t provide the benefits of TypeScript’s safety features.
- Explain the concept of generics in TypeScript.
- Generics are like placeholders for types. They allow you to write code that works with different types without sacrificing type safety.
- How does TypeScript work with popular JavaScript libraries or frameworks?
- TypeScript can be used with libraries and frameworks by adding types to them. This helps you use these tools more safely and with fewer surprises.
- What is the TypeScript compiler, and what does it do?
- The TypeScript compiler is like a translator. It takes your TypeScript code and turns it into regular JavaScript so that browsers or other environments can understand and run it.
