What are the differences between TypeScript utility types?

Can you explain the differences between TypeScript utility types like Partial, Pick, and Omit?

Sure! In TypeScript, utility types help manipulate types easily.

• Partial<T> makes all properties in T optional.
• Pick<T, K> creates a type by picking a set of properties K from T.
• Omit<T, K> creates a type by omitting a set of properties K from T.

Can you give me an example of how to use these utility types?

Absolutely! Here's a quick example:

interface User {
  id: number;
  name: string;
  email: string;
}

const userPartial: Partial<User> = { name: 'Alice' }; // Only name is provided
const userPick: Pick<User, 'name' | 'email'> = { name: 'Bob', email: '[email protected]' };
const userOmit: Omit<User, 'id'> = { name: 'Charlie', email: '[email protected]' };

What are some other utility types I should know about?

Other useful utility types include:

• Required<T>: Makes all properties in T required.
• Readonly<T>: Makes all properties in T readonly.
• Record<K, T>: Creates an object type with keys of type K and values of type T.
