Description
We'll get a really good performance boost if we replace new URL, which is used too much often as I see, with string methods. On the other hand, manually parsing URL in some cases is not simple and concise.
Benchmark code
const Benchmarkify = require("benchmarkify")
const benchmark = new Benchmarkify("Benchmark", { chartImage: true }).printHeader()
benchmark.createSuite("URL convert", { time: 10000 })
.add("URL object", () => {
const url = new URL("https://dc09.ru/posts/fediverse#comments")
const hash = url.hash
url.hash = ""
return encodeURIComponent(url.toString()) + hash
})
.ref("String methods", () => {
let url = "https://dc09.ru/posts/fediverse#comments"
const hashIdx = url.indexOf("#")
if (hashIdx != -1) {
return encodeURIComponent(url.substring(0, hashIdx)) + url.substring(hashIdx)
}
else {
return encodeURIComponent(url)
}
})
