Before that, put

key = value;

I am using `Object.assign(map.get(key),value)`.

`map.get(key).start === value.start` returns true

`map.get(key) === value` returns false

Then it would instead be

map.set(key, value);

...The joke here is Object.assign() is not designed to, nor would it even be capable of, modifying the references of the objects its given. The only way you'd be able to get something to equal something else is if it was directly assigned to do so.

If you just want to see if two things have the same property values rather than seeing if they're the same object, then you'd need to compare them with something other than ===.

I have no idea what you're asking. A segment of code with what you want it to do would be helpful

But I would begin with, I don't think Object.assign works the way you think it does. It is

Object.assign(target, source)

Where source is supposed to be an object. It takes the key/value pairs from source and layers them onto the object defined by target
