WebbFor example, it must be able to choose the correct production from the start symbol based on the first token in the input. This limitation motivates bottom-up parsing, in which the parser can choose productions after seeing more input. For example, bottom-up parsers can handle left-recursive productions whereas top-down parsers cannot.
