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...

Yes, arrays are a shitty datastructure. Breaking news! Hardly anyone uses them these days. There are plenty of efficient, enlargeable purely functional data structures like finger trees.
