Narrative:
On takeoff at approximately 4000 ft MSL; we heard three loud pops out of the left engine. We disengaged the auto throttles and the autopilot and determined that we had a compressor stall on the left engine. We declared an emergency and requested vectors to return to land. All the checklists were performed and we landed with no event. The fire trucks inspected the engine and saw no issues with us taxiing back to the gate. Maintenance met the aircraft and it was taken out of service. We spoke with the chief pilot on duty and determined that we were fit to fly to our destination for one leg.
