+> I want to sort by the attribute Age, from youngest to oldest but all of the NULL values are treated as the lowest value. I would much prefer sorting to ignore these empty fields..
+
+Javascript is weird, and we'd have to do something like the following to sort with ages:
+
+```
+myarr.toSorted((a, b) => {
+ if(a == null) {/*isNumber(null) = true*/
+ return 1;
+ }
+ if(b == null) {
+ return -1;
+ }
+ if(isNumber(a) && isNumber(b)) {
+ return a - b;
+ }
+});
+```
+
+to ensure that null values always come last.
+
+Mixed lists are going to have to be sorted in alphabetical order, I guess, while still ensuring nulls end up last with something like the above.
