Implement a "No Operation" Function in JavaScript

In software development, it's often useful to have a placeholder function that does absolutely nothing. This is commonly known as a "No Operation" or "noop" function. Such functions are invaluable when dealing with optional callbacks, default behavior, or when you need to temporarily disable a piece of logic without extensive code modification. Your task is to create a robust and versatile noop function in JavaScript.

Problem Description

Your goal is to implement a JavaScript function named noop that accepts any number of arguments and performs no action, returning undefined.

Key Requirements:

• The function must be named noop.
• It should accept any number of arguments.
• It should not perform any side effects (e.g., logging, modifying global state, etc.).
• It should always return undefined.

Expected Behavior:

When noop is called, regardless of the arguments passed to it, its execution should be instantaneous and have no observable outcome other than returning undefined.

Edge Cases:

• Calling noop with no arguments.
• Calling noop with various data types as arguments (numbers, strings, objects, arrays, functions, null, undefined).

Examples

Example 1:

noop();

Output: (No output is printed to the console. The function simply returns undefined.)

Explanation: The noop function is called without any arguments. It performs no operation and returns undefined.

Example 2:

const result = noop("hello", 123, { a: 1 }, [4, 5]);
console.log(result);

Output:

undefined

Explanation: The noop function is called with multiple arguments. It ignores all of them, performs no action, and returns undefined, which is then logged to the console.

Example 3:

function processData(data, callback = noop) {
  // ... some data processing ...
  callback(); // Execute the callback, which might be noop or a real function
  return "processed";
}

console.log(processData("some data"));

Output:

processed

Explanation: When processData is called without providing a callback, the default noop function is used. This demonstrates how noop can be used as a safe default for optional callbacks. The function executes, noop is called (doing nothing), and "processed" is returned.

Constraints

• The solution must be written in plain JavaScript.
• The function should be efficient and have minimal overhead.
• No external libraries or frameworks are allowed.

Notes

Consider how JavaScript handles functions that accept an arbitrary number of arguments. The arguments object or rest parameters (...args) are common ways to achieve this. Think about the simplest possible implementation that fulfills all the requirements.
