Logs the current value of a timer that was previously started by calling console.time()
to the console.
See Timers in the documentation for details and examples.
Note: This feature is available in Web Workers.
Syntax
console.timeLog(label);
Parameters
label
- The name of the timer to log to the console.
Return
If no label parameter included:
default: 1042ms
If an existing label
is included:
Exceptions
If there is no running timer, timeLog()
returns the warning:
Examples
console.time("answer time"); alert("Click to continue"); console.timeLog("answer time"); alert("Do a bunch of other stuff..."); console.timeEnd("answer time");
The output from the example above shows the time taken by the user to dismiss the first alert box, followed by the time it took for the user to dismiss the second alert:
Notice that the timer's name is displayed when the timer value is logged using timeLog()
and again when it's stopped. In addition, the call to timeEnd() has the additional information, "timer ended" to make it obvious that the timer is no longer tracking time.
