Can you explain what TypeScript type annotations are?
Type annotations in TypeScript are a way to specify the types of variables, function parameters, and return values. They help catch errors at compile time.
Why should I use type annotations instead of just using JavaScript?
Using type annotations can improve code quality and maintainability by providing better tooling support, catching errors early, and making the code more understandable.
Can you give me an example of how to use type annotations?
Sure! For example, you can define a function like this: function greet(name: string): string { return 'Hello, ' + name; }
Here, name
is annotated as a string.
What happens if I don't use type annotations?
If you don't use type annotations, TypeScript will infer types based on the values you assign, but you may lose some type safety and clarity in your code.
