Merge Objects

Merge two objects into a new one; properties in the second override the first.

Examples

  • mergeObjects({a:1,b:2}, {b:3}) → {a:1,b:3}

Constraints

  • Keep the required function name so the tests can find it
  • Return a value instead of only logging it
  • Do not mutate inputs unless the challenge asks you to

Code runs in an isolated Web Worker with a 3-second timeout — no DOM access, and it can never hang the page.
