This video provides an explanation of how regular expression quantifiers work. It covers greedy, lazy and possessive quantifiers. Various examples and diagrams are provided. The explanations focus on considering a quantifier as a 'range' that specifies the minimum and maximum number of times a part of the regex should be repeated. A detailed explanation of the concept of backtracking is also provided.
