Hi,
Wondering if someone can help with a bit of context to satisfy mu
curiosity! :D
We are using Date.now & new Date quite a bit in our application (financial
domain). I run a few micro-benchmarks and was wondering why do these report
being relatively slow (as compared to construction of other objects). In
fact all Date methods seem rather slow. Am I having wrong expectations for
these to be faster? Are they as fast as they could be, or is it that Date
just never got enough love in terms of performance optimizations? Really
curious to get more color on this!
Benchmarks:
Date.now() x 9,454,436 ops/sec ±1.09% (65 runs sampled)
new Date() x 5,594,688 ops/sec ±1.87% (64 runs sampled)
[1, 2, 3] x 124,719,052 ops/sec ±0.90% (64 runs sampled)
{ a: 1, b: 2, c: 3 } x 112,368,878 ops/sec ±0.83% (65 runs sampled)
new Object({ a: 1, b: 2, c: 3 }) x 32,547,566 ops/sec ±0.64% (64 runs
sampled)

Thanks!
