Conditional Types

Conditional Types in TypeScript are a powerful tool that allows developers to create types that vary based on the type of a given variable or expression. This can be useful for a variety of purposes, such as creating custom types that enforce certain constraints, or creating types that are more specific to a particular use case.

Why Learn Conditional Types?

There are several reasons why you might want to learn about Conditional Types in TypeScript.

• To create custom types that enforce certain constraints. Conditional Types can be used to create types that can only be assigned values that meet certain criteria. This can be useful for ensuring that your code is type-safe and that it meets your requirements.
• To create types that are more specific to a particular use case. Conditional Types can be used to create types that are tailored to a specific use case. This can make your code more readable and maintainable.
• To improve the performance of your code. Conditional Types can be used to optimize the performance of your code by avoiding unnecessary type checks.
