LL grammars, particularly LL(1) grammars, are of great practical interest, as parsers for these grammars are easy to construct, and many computer languages are designed to be LL(1) for this reason.[8] LL parsers may be table-based,[citation needed] i.e. similar to LR parsers, but LL grammars can also be parsed by recursive descent parsers. According to Waite and Goos (1984),[9] LL(k) grammars were introduced by Stearns and Lewis (1969).[10]
