BreakTime | Aggressively forces you to take breaks every x minutes | BPM library

I'm new to javascript and I'm trying to make a piechart that get the input from the user.

I did what I thought was correct but the chart does not come out.

When I put the variable it doesn't recognize the code that I have put in even though I already have imported the Chart.js using CDN, that they provide on their website.

I'm trying to get the percentage from the "timeSpend" and "breakTime" and store in fSubject,sSubject, tSubject and store it in dataset: date[], so that it can output it but it just gives the value of "timeSpend" and "breakTime" not fSubject,sSubject, tSubject. Also the colour is not working I don't know why enter image description here

I am trying to complete the FreeCodeCamp 25 + 5 clock project with React. When I website runs the project tests, it says that the timer is not reaching 00:00, even though when I click play, it clearly reaches 00:00.

I am wondering if I am having this issue because of some sort of drifting? How would I go about fixing that?

Thank you.

I also tried a version where i use SetTimeout and implement this Stack overflow answer (setInterval timing slowly drifts away from staying accurate), but it still wouldn't pass the test. See that codepen: https://codepen.io/Jamece/pen/mdqGomq

I also tried delaying the this.atZero function 1 second and that didn't work

My Code:

I am having trouble creating a JavaScript timer using. I have tried to implement things from other stack overflow questions and haven't had any success.

When I click the play button, "0-8:0-46" is displayed instead of the actual timer. And it does not count down.

My Code thus far is below. I am trying to troubleshoot the sessionTimer function right now.

It's the first time a use Flutter (2.8.1) and I'having problems trying to undestrand what's going wrong.

I have a Stateful widget like this:

I have an array of objects in javascript where I have employees login timings. I want to find if an employee has worked more then 5 hours consecutively then he/she will get a break. Otherwise if an employee worked more than 5 hours, but not consecutively, then they do not get a break.

Here is the code - it currently is just checking the number of hours an employee has worked, but it is not checking for consecutive hours.

Following is my table:

what im trying to do is that i have a branch that got workhours and so there is more than one services this branch give , so if the client press on service that its duration 15 minutes i need to divide the work hours of the branch into queue list of this duration , from open shift till endshift and also delete all the queues that are on breaktime of the branch

i have this variables:

Startshift="09:10" , breaktime = "12:00" , endBreak="12:30" , endShift="13:00" , period each :10min

i want to define an array of time periods that contain in each cell specific hour according to specific variable i give

myCode:

I need to create a function that excepts 2 parameters arrays of times and return true or false if the second array between one of the times of the first array:
