Implement Promise Race

Implement a function promiseRace that mimics the behavior of Promise.race(). It takes an array of promises (or values) and returns a promise that settles (either resolves or rejects) as soon as the first input promise settles.

Input:

• An array of promises or values

Output:

• A single promise that resolves/rejects with the result/error of the first settled promise

Example Inputs & Outputs

// Example 1:
Input: [Promise.resolve(1), Promise.resolve(2)]
Output: Resolves with 1

// Example 2:
Input: [Promise.reject('error'), Promise.resolve(2)]
Output: Rejects with 'error'

// Example 3:
Input: [42, Promise.resolve(10)]
Output: Resolves with 42 (since 42 is a non-promise value)

// Example 4:
Input: []  
Output: Never settles (same as native Promise.race)

Constraints & Edge Cases

• Input can contain both promises and non-promise values.
• The result should reflect the first settled item.
• If input is empty, the returned promise should never settle.
• Input may include a mix of resolved, rejected, and pending promises.
