Extended clock

We've got a Clock class. As of now, it prints the time every second.

[js src="source.view/clock.js"]

Create a new class ExtendedClock that inherits from Clock and adds the parameter precision -- the number of ms between "ticks". Should be 1000 (1 second) by default.

  • Your code should be in the file extended-clock.js
  • Don't modify the original clock.js. Extend it.
