Cycle, adding numbers to 100 after they drop to 0 [closed]

Question

It is necessary to make the addition of numbers to 100 after they fall to 0.

battery(100, document.getElementById('battery')); function battery( percent, elem ) { if(percent !== 0) { setTimeout(() => { percent < 0 ? battery(++percent, elem) : battery(--percent, elem); }, 100); } elem.innerText = percent + '%'; }

Specify what it means to “output” insert the value resulting from the function or insert the function into “div” in the line itself, or (once the battery) is a block that is in another block and occupies the width / height of the container
and yes, it's not very clear how this function can do anything at all, it's a cycle that does nothing
you equate percent zero, after which none of the conditions is fulfilled and the function will be called after a timeout and it will be exactly the same ... this is a meaningless function.
There will be no value ... all the time, setTimeout (battery, 100) will be called;

It is not very clear what it is and why it is, but perhaps something like this is required ...

 battery(100, document.getElementById('battery-1')); battery(0, document.getElementById('battery-2')); battery(-100, document.getElementById('battery-3')); function battery( percent, elem ) { if(percent !== 0) { setTimeout(() => { percent < 0 ? battery(++percent, elem) : battery(--percent, elem); }, 100); } elem.innerText = percent + '%'; }

 <div id="battery-1"></div> <div id="battery-2"></div> <div id="battery-3"></div>

How can I put this into the html div? After all, I have come to court for this, and thanks for the code.
C'mon, I generally expected that they would answer only tomorrow, thank you very much.

@AndreyNikonov and where in your question is the part about reaching the value up to 100, and then back to 0?
