Andreas Kling	7dc78b5e38	LibJS: Use correct |this| value when getting/setting native properties	2020-03-24 16:14:10 +01:00
Andreas Kling	343e224aa8	LibJS: Implement basic exception throwing ... You can now throw exceptions by calling Interpreter::throw_exception(). Anyone who calls ASTNode::execute() needs to check afterwards if the Interpreter now has an exception(), and if so, stop what they're doing and simply return. When catching an exception, we'll first execute the CatchClause node if present. After that, we'll execute the finalizer block if present. This is unlikely to be completely correct, but it's a start! :^)	2020-03-24 16:14:10 +01:00
Andreas Kling	cccbe43056	LibJS: Use FlyString for identifiers ... This makes variable and property lookups a lot faster since comparing two FlyStrings is O(1).	2020-03-22 13:03:43 +01:00
Andreas Kling	324b92fd06	LibJS: Virtualize access to an Object's own properties ... Object now has virtual get_own_property() and put_own_property() member functions that can be overridden to provide custom behavior. We use these virtuals to move Array-specific access behavior to Array.	2020-03-21 14:37:34 +01:00
Andreas Kling	a82f64d3d6	LibJS: Parse ArrayExpression and start implementing Array objects ... Note that property lookup is not functional yet.	2020-03-20 21:56:40 +01:00
Andreas Kling	19452230cd	LibJS: Add "Heap" and "Runtime" subdirectories ... Let's try to keep LibJS tidy as it expands. :^)	2020-03-16 14:37:19 +01:00
