Filtering from array elements

I am trying to filter a few items out of an array. So far I have been able to filter an item in the array, but if I want to remove a child from the array element I am unable to do so. In the example below chartsArray has code value Age_Total. In array el I have this string Age_Total and when I filter it is removed. But I also have a field Q0120F_18P which doesn't get filtered. You can still see this element in the fourth array element under Age_Female . So my question is how can I iterate through chartsArray where it can filter the parent array element as well as the child element.

You could filter the children with a recursive call and assign it inside of the filter callback.

chartsArray = chartsArray.map(a => a.filter(function code(o) {
    if (!el.includes(o.code)) {
        if (o.children) {
            o.children = o.children.filter(code);
        }
        return true;
    }
}));
