Choosing & comparing

Same feature, both architectures, side by side

Both architectures ship serious products. Neither is wrong. The mistakes that hurt projects aren't 'I picked the wrong one' — they're 'I picked one and didn't follow its rules', 'I tried to mix them', and 'I picked for emotional reasons instead of constraints.' This chapter gives you a five-question decision framework, the same feature implemented in both architectures so you can see the diff with your eyes, and an honest verdict on each trade.
