19 | * This is not as optimal as the original SO answer (we split into per-word),

20 | * however it does pass the tests (which the SO version doesn't) and is still
|
21 | * a major improvement over the original camelcase npm package -

23 | * camelcase: 20.88 μs/op
|
24 | * this: 1.00 μs/op

25 | *
|
26 | * Caveat of this: only Ascii, but acceptable for the intended usecase
