Arrow Function Style Guideline

All functions in this codebase must be written as arrow functions assigned to const variables. Do not use function declarations or function expressions.

Correct:

const greet = (name: string): string => {
  return `Hello, ${name}`;
};

const double = (x: number) => x * 2;

Incorrect:

function greet(name: string): string {
  return `Hello, ${name}`;
}

const double = function(x: number) { return x * 2; };

When writing new functions or modifying existing ones, always use the arrow function form. If you encounter function declarations in code you are editing, convert them to arrow functions.
