The console.time()
method starts a timer you can use to track how long an operation takes. You give each timer a unique name, and may have up to 10,000 timers running on a given page. When you call console.timeEnd()
with the same name, the browser will output the time, in milliseconds, that elapsed since the timer was started.
See Timers in the console
documentation for details and examples.
