TypeScript supports a handful of built-in types; the following are examples of the most common ones:
const fullName: string = "John Doe";const age: number = 6;const isDone: boolean = false;const d: Date = new Date();const canBeAnything: any = 6;
As you can see, TypeScript supports basic primitive types such as string, number, boolean, and date.
Another thing to notice is the type any. The any type is a valid TypeScript type that indicates that the declaration can be of any given type and all operations on it should be allowed and considered safe.
