TypeScript has become the industry standard for large-scale JavaScript applications. Beyond basic types, mastering advanced patterns can significantly improve type safety and developer productivity.

**Template Literal Types:**
Create type-safe strings with template literal types, allowing you to define complex string patterns that are checked at compile time.

**Mapped Types:**
Transform existing types into new shapes using mapped types. This is particularly useful for creating derived types from existing interfaces.

**Conditional Typing:**
Write type-level conditional logic that determines the type of a value based on the type of another value.

**Type Guards:**
Use type guards to narrow down the type of a value within a specific scope, making your code safer and more maintainable.

**Utility Types:**
Leverage TypeScript's built-in utility types to simplify common type transformations, such as `Partial`, `Required`, and `Omit`.

By mastering these advanced features, you can write more robust, type-safe code that is easier to maintain and scale.
