JS array sorting: how to use the sort() method
Article Introduction:JavaScript's Array.prototype.sort() method is used to sort the elements of an array. This method sorts in place, that is, it modifies the original array rather than returning a new sorted array. By default, the sort() method sorts strings according to their Unicode code point values. This means that it is used primarily for sorting strings and numbers, rather than for sorting objects or other complex data types.
