Spawn game objects from array to array of transforms

Hey guys! I need help in instantiating objects in a transform. Currently, what I want to do is when an enemy dies, it will spawn new enemies (which are in an array) in "fixed" positions (also in an array).

Eventually, what I want to happen is that enemy 1 will spawn at position 1, enemy 2 at position 2, and so on. I suppose I could go with:

 GameObject enemy1 = Instantiate(SpawnedEnemies[1], SpawnLocations[1].position, SpawnLocations[1].rotation);
 
 GameObject enemy2 = Instantiate(SpawnedEnemies[2], SpawnLocations[2].position, SpawnLocations[2].rotation);
 
 GameObject enemy3 = Instantiate(SpawnedEnemies[3], SpawnLocations[3].position, SpawnLocations[3].rotation);
 
 // and so on...

...but then, apart from it being expensive to run, there won't be any flexibility in doing this.
Anyway, any and all help will be appreciated.
