WebApr 10, 2024 · Left-Recursion: Top-down parsers can suffer from left-recursion, which can make the parsing process more complex and less efficient. Look-Ahead Restrictions: Some top-down parsers, such as LL(1) parsers, have restrictions on the number of look-ahead symbols they can use, which can limit their ability to handle certain types of grammars.
