NOTE: Swift and Go do not seem to use Tail Call Optimization so this may be why they are showing up as twice as slow. Thank you Ammrage for pointing this out.

The following code examples use techniques that break the benchmark. They do not perform the same internal tasks as the other examples so are not a good apples to apples comparisons. It demonstrates that all benchmarks will have some caveat.
| Language | Time, s | Compile | Run |
|---|---|---|---|
| Go (mem) | 0.005* | go build -o fib fib-mem.go |
time ./fib |
| Nim (mem) | 0.006* | nim cpp -d:release fib_mem.nim |
time ./fib_mem |
| C++ (constexpr) | 0.086* | g++-8 -O3 -o fib fib-constexpr.cpp |
time ./fib |
| Node (mem) | 0.112* | time node fib-mem.js |
NOTE:
The C++ (constexpr) is using a constexpr which optimizes the recursive call to a constant. It was provided by Ole Christian Eidheim.
The Go (mem) is using memoization. It was provided by Alexander F. Rødseth.
The Node (mem) is another example using memoization. It was provided by YSTYLE-L.X.Y
The Nim (mem) version is provided by PMunch
