Programmers love to think about optimizing code. Should we use .forEach() or for()? What's the Big-O of this algorithm?
I tend to value a programmer's time as more scarce than money. It's hard to hire great programmers so the bottleneck of a company's R&D is usually time, not money.
Therefore I gladly pay double price for cloud servers and focus on usecase instead of optimizated code.
Code readibility also plays a big role here. Prefer to write simple code that's easy for another developer to contribute to.
