将console.time结果写入variables

是否有可能写console.time()结果到variables？

 console.time('It\'s saved!'); fn(); var a = console.timeEnd('It\'s saved!'); console.log(a) // => It's saved!: 16ms

不，但是可以使用window.performance.now()来代替

 var t0 = performance.now(); doSomething(); var t1 = performance.now(); console.log("Call to doSomething took " + (t1 - t0) + " milliseconds.")
