Promise.all(), Promise.race(), and Promise.any()

Promise.all() with empty array has specific behavior: 1) Resolves immediately, 2) Returns empty array as resolved value, 3) Follows mathematical principle of vacuous truth, 4) Consistent with parallellism concept where no tasks means all tasks complete, 5) Safe to use in dynamic situations where input array might be empty, 6) Useful edge case handling in array operations.
