TypeScript’s narrowing and type guards are essential features that enhance code integrity and safety. Narrowing allows for more precise type checking by refining inferred types based on conditions or type relationships.
Type guards act as conditional statements or functions that determine whether a value conforms to a specific type, enabling developers to write code that takes advantage of the narrowed type.
These features provide benefits such as improved code readability, early error detection, and intelligent code completion. By embracing narrowing and type guards, developers can create safer and more reliable TypeScript codebases.
Let’s understand about them in detail in this video.
