Promodoro clock - need help

Tell us what’s happening:
my console says accurateInterval not defined. Do I have to add a separate function for this or Am I missing a library?

Your code so far

Challenge: Build a Pomodoro Clock

Link to the challenge:
https://www.freecodecamp.org/learn/front-end-libraries/front-end-libraries-projects/build-a-pomodoro-clock

I missed this at first too. But it’s explained in the comment of the codepen supplied by the challenge:
“Dependencies are React, ReactDOM, and
Accurate_Interval.js by Squuege (external script **
** to keep setInterval() from drifting over time & **
** thus ensuring timer goes off at correct mark)
.”

In the pen settings under JavaScript, you can add the following link:

This defines accurateInterval for you I believe.

Hope that helps!
