Create Hello World Function

Write a function createHelloWorld that returns a new function. This returned function should always return "Hello World" no matter what arguments are passed to it.

How to Solve

Return an arrow function that ignores all arguments and returns the constant string "Hello World". This demonstrates closure and function factories in JavaScript/TypeScript.

Code

const createHelloWorld = (): () => string => {
  // Your implementation here
};

Test Cases

Input 1

const hello = createHelloWorld();
hello();

Expected Output: "Hello World"

Input 2

const hello = createHelloWorld();
hello(1, 2, 3);

Expected Output: "Hello World"

Input 3

const hello = createHelloWorld();
hello("foo", "bar", { baz: "qux" });

Expected Output: "Hello World"

Complexity

Time Complexity: O(1) - Constant time operation, just returning a string.

Space Complexity: O(1) - Constant space, no additional data structures needed.
