These measures are JS performance are important for VM implementors, for people writing node.js applications to be used at large scale and people doing computationally-complex work in the browser (eg creating physics engines). It's worth noting that for most of us, most of the time, this kind of JS performance is less important than user-perceptible optimizations, like batching DOM reads and writes and decreasing asset size
