testperf

An easy speed test for JavaScript.

Takes 2 arguments (name, function), and then any additional arguments are passed to the function being tested.

Example:

const flatMap = require("flatmap-fast")
 
testPerf("flatMapFast", flatMap, ["Hi", "World"], word => word.split(""))
 
// => flatMapFast took: 622.593672 milliseconds.

As of v2.0.3, node and native browser JavaScript are supported, using either performance.now() or process.hrtime(). process.hrtime() is formatted to match performance.now()'s output'.
