Did you know Ruby optimizes your code before executing it? If so, ever wonder how that works? The Ruby VM performs various optimizations on bytecode before executing them, one of them called peephole optimizations. Let’s learn about how some peephole optimizations work and how these small changes impact the execution of Ruby’s bytecode. Do these small changes make any impact on the final runtime? Let's find out - experience reading bytecode is not needed!
