console.timeLog([label][, ...data])


    对于先前通过调用 console.time() 启动的计时器,将经过时间和其他 data 参数打印到 stdout

    For a timer that was previously started by calling console.time(), prints the elapsed time and other data arguments to stdout:

    console.time('process');
    const value = expensiveProcess1(); // Returns 42
    console.timeLog('process', value);
    // Prints "process: 365.227ms 42".
    doExpensiveProcess2(value);
    console.timeEnd('process');
