#ecmascript#hacktoberfest#interpreter#javascript#javascript-engine#javascript-interpreter#parser#runtime#rust#rust-crate#wasm#webassembly
Boa can't parse a class with a keyword as name over 1 year ago

AI Summary: The task is to debug and fix a parsing error in the Boa JavaScript engine. The engine currently fails to parse a JavaScript class declaration where the class name is a reserved keyword ('of'). The solution requires understanding the Boa engine's parser, identifying the source of the parsing error related to keyword usage as class names, and implementing a fix to correctly handle such cases.

Complexity: 4/5
