Benchmark: RequireJS paths processing

Script Preparation code:

const pathMap = new Map()
pathMap.set('test', 'site/app')
pathMap.set('vendor', 'site/vendor')
window.pathMap = pathMap
window.testId = 'test/lib/alpaca/js/alpaca'

Tests:

path part splitting and joining
const pathMap = window.pathMap const parts = window.testId.split('/') let modified for (let { length } = parts; length > 0; --length) { const parent = parts.slice(0, length).join('/') const path = pathMap.get(parent) if (path) { parts.splice(0, length, path) modified = true break } } const mapped = parts.join('/')
looking up path separators
const pathMap = window.pathMap let mapped = window.testId for (let separator = mapped.length;;) { const parent = mapped.substr(0, separator) const path = pathMap.get(parent) if (path) { mapped = `${path}${mapped.substr(separator)}` break } separator = mapped.lastIndexOf('/', separator - 1) if (separator < 0) break }
