Javascript stopwatch error

let sw = new Stopwatch()
I am having a problem with the object creation. I declare a stopwatch but it says:
“Uncaught ReferenceError: Stopwatch is not defined”

That’s what happens for me too. As far as I know, there is no built-in Stopwatch class.

This is chapter 14? It’s an excercise, you have to create Stopwatch yourself. See chapter 15 for the solution.

try const instead of let

Has anyone successfully implemented the stopwatch exercise (exercise 14)?
I copied exactly what the instructor (on lesson 15) has but not getting it to work properly.

const sw = new Stopwatch();
Then
sw.start ----> get the function source code on console rather than output.

sw.stop ---->get the function source code on console rather than output.

sw.duration ----> OK. Always get 0

Anything I am doing wrong to get the source code rather than the output?

Thanks for chiming in.

I think you need to call the functions, for example

sw.start()
sw.stop()

Notice the parentheses.

Thank you eelsholz!

That was it. I also did not use "const sw = stopwatch(); "
to start with. Thanks for catching it for me. Practice makes perfect!
