I need some help understanding something in my screenshot.
Although both tmpStart and itemDate have been assigned the same numeric value, they display different calendar dates.
https://i.sstatic.net/N4C0j.png
Any advice would be greatly appreciated!
const newStart = new Date(start);
start += itemSize; // updated start value
// reassigned item as start (updated)
let newItemDate = new Date(item);
// hence
newStart !== newItemDate
That is the reason.
Adopt functional programming. Avoid using assignment. :) (start += itemSize)
Every time you call new Date(), a unique instance of the date is created, ensuring they are different each time.
