I want to understand how the sort() method functions. Specifically, I'm curious about the sorting algorithm it employs, the order of sorting, and whether it sorts in ascending or descending order by default.

The sort() function operates by utilizing a compare function to determine the ordering of values. When tasked with comparing two values, it dispatches these values to the compare function for analysis.

The compare function then assesses the input values and returns a numerical outcome indicating their relative positioning. This outcome can be negative, zero, or positive, each signifying a different sorting preference.

If the compare function yields a negative result, it instructs the sort() function to place the first value (a) before the second value (b) in the sorted sequence. This indicates that a is considered to be less than b according to the comparison criteria.

Conversely, when the compare function returns a positive result, it signals to the sort() function that the second value (b) should precede the first value (a) in the sorted order. This signifies that b is greater than a based on the defined comparison rules.

A zero result from the compare function signifies equivalence between the two values. In such cases, the specific ordering of a and b may vary depending on the sorting algorithm's stability, but they are considered to be of equal significance in terms of their sorting position.
