Multiple conditions on a single field

[PeterEsenwa]

Given this snippet (it's part of a function I use to get conditions for a given User)

...
    if (currentUser.assignedState && currentUser.assignedState.length > 0) {
        filterObject = {
            ...filterObject,
            assignedState: {
                $in: currentUser.assignedState,
            },
        };

        if (currentUser.assignedLga && currentUser.assignedLga.length > 0) {
            filterObject = {
                ...filterObject,
                assignedLga: {
                    $in: currentUser.assignedLga,
                },
            };
        }
    }
...

I would like to know how I can use multiple queries ($in and $exist) with the assignedState and assignedLga fields in the provided code snippet?”

It seems that you just need this:

filterObject = {
                ...filterObject,
                assignedLga: {
                    $exists: true,
                    $in: currentUser.assignedLga,
                },
            };
