That's a rather fatuous test though, you're comparing the execution *and compilation* time there which is obviously going to cost method 1 (compiles N times, JS engine depending) with method 2 (compiles once). I can't imagine a JS developer who would pass their probation writing code in such a manner.

Your $index variable there kind of misleading. That number isn't the index, your "A", "B", "C", "D" keys are. You can still access the data through the numbered index $index[1], but that's really not the point. If you really want to keep the numbered index, I'd almost restructure the data:
