function-type-expressions

What problem does it solve?

Repeatedly writing the same function signature across multiple function expressions leads to noise and maintenance burden. This skill lets you define the signature once and apply it to all relevant functions.

Core Features & Use Cases

• Define a single function type alias and reuse it across several expressions.
• Use typeof to match an existing function's signature exactly.
• Use Parameters to derive argument types when wrapping or composing functions.
• Improve readability and safety by centralizing return and parameter types.

Quick Start

Create a shared type for your common signature and apply it to all related function expressions.
