Omitting specific fields in TypeScript types

TypeScript has an Omit utility type that lets you create a new type by excluding specific keys from an existing type. It's perfect for cases where you need a type that's almost the same but without certain properties.

Here's an example:

type User = {
  id: number;
  name: string;
  password: string;
};

type PublicUser = Omit<User, 'password'>;

Now we have a PublicUser type that includes id and name, but the password field is excluded.
