Before we dive into the main topic, let’s take a step back and understand what utility types are. In TypeScript, utility types are a set of predefined types that help you perform common type transformations. They’re like Swiss Army knives for your type system – versatile, flexible, and incredibly useful.
Some common examples of utility types include:
Pick
: picks a subset of properties from an object type
Omit
: omits a subset of properties from an object type
Partial
: makes all properties of an object type optional
Required
: makes all properties of an object type required
These utility types are essential in shaping your type system to fit your specific needs. But what if you want to take it to the next level and turn a utility type into a literal type?
