Protip: Compute the size before you allocate

I've lost track of how many times I've seen code that uses a dynamically-expanding array when it could've easily calculated the correct size and allocated exactly the right amount. See: string appending, tokenising, just about everything written in JavaScript, etc.

No wonder software is so slow and bloated...

Cudder-san,
1. B-Trees with forwarding links at the leaves
2. Counting cycles is valid, but...
3. JS is not for microcontrollers
4. I would cry in joy if adding elements took 0 cycles
5. Some resizes may not need copying
6. Serious strings are not byte arrays
7. Imperative foreach instead of functional Array.join() deserves Lv.10 Slow!
