Benchmark: For Loop Approaches

Script Preparation code:

num = i => i * 19 - 3

Tests:

for loop - (initialize counter above)
let i = 0; const length = 1000; for(i; i < length; i++) { return num(i); };
for loop - (inline initialized counter)
const length = 1000; for(i; i < length; i++) { return num(i); };
for loop - (i += 1)
let i = 0; const length = 1000; for(i; i < length; i += 1) { return num(i); };
