Those JS methods I used for the first time (updated)

1. The console. Time (label) and the console. TimeEnd (label)

• Description: Prints the time between the run of console.time and the run of console.timeEnd
• parameter:
  
  label: Label name (Optional). The same label name must be used for the time and Timend groups
• Purpose: Test the duration of program execution

Console. time('aaa') // Start method of calculator // test code... Console. timeEnd('aaa') // End method for calculatorCopy the code
