How does type checking work in TypeScript?

Can you explain how type checking works in TypeScript?

Type checking in TypeScript ensures that variables are used consistently with their defined types, helping to catch errors at compile time.

What are the different types of type checking in TypeScript?

TypeScript primarily uses static type checking, but it also supports dynamic type checking through type assertions and the 'any' type.

How does TypeScript handle type inference?

TypeScript can automatically infer types based on the assigned values, reducing the need for explicit type annotations.

Can you give an example of type checking in action?

Sure! If you declare a variable as a number and then try to assign a string to it, TypeScript will throw a compile-time error.
