2197+
2198+
The `compareFcn` determines the order of the elements. The function is called with the following arguments:
2199+
2200+
- **a**: the first element for comparison.
2201+
- **b**: the second element for comparison.
2202+
2203+
The function should return a number where:
2204+
2205+
- a negative value indicates that `a` should come before `b`.
2206+
- a positive value indicates that `a` should come after `b`.
2207+
- zero or `NaN` indicates that `a` and `b` are considered equal.
