Go maps vs switches

A benchmarking comparison of Go switch statements versus map lookups for value mapping. When mapping ints to strings, switch is nearly 10x faster than maps due to simple comparisons vs runtime map access calls. When mapping strings to ints, both perform similarly. The switch has O(N) complexity while maps offer O(1), meaning the best choice depends on the number of elements, readability needs, and performance requirements. The key takeaway is to benchmark rather than assume.
