if (this.solvedConflictsDetails[this.instance.instanceId][this.model.name][this.entity.entityId].solved)
The problem is that if one of the above doesn't exist in the object it will say cannot read undefined
How would you check a condition like this?

When I create an array of empty arrays with the following code:
const arrayOfArrays = new Array(3).fill([])
As expected, I get [[],[],[]. However let's say I change the value with:
arrayOfArrays[0][0] = 'foo'
I expect to get [['foo'],[],[]] but I end up with [['foo'],['foo'],['foo']]. Why is this the case? How can I get it so that it works as expected?

In Java it's called the keyset.
https://www.npmjs.org/package/node-hashtable
how come there is no method to return a list of all the keys?
Looking at the source there seems to be a method indexes which returna a list of the keys.
