next: an element next to $('')
nextAll: all sibling elements after $('')
nextUntil: until. . . The previous meaning, so it means all sibling elements after $(''), but before the nextUntil parameter, excluding the matching element itself
sibings: all sibling elements before and after $('')
The simple understanding is that next is to find his younger brother/sister, nextAll is to find all his younger brothers/sisters, nextUntil is to find younger brothers/sisters who are a certain age younger than him, siblings is to find all his brothers/ Sister, and all his brothers/sisters. So the same peer relationship, prev, prevAll, prevUntil
