LibJS+LibWeb: Add JS::Object::inherits(class_name) To allow implementing the DOM class hierarchy in JS bindings, this patch adds an inherits() function that can be used to ask an Object if it inherits from a specific C++ class (by name). The necessary overrides are baked into each Object subclass by the new JS_OBJECT macro, which works similarly to C_OBJECT in LibCore. Thanks to @Dexesttp for suggesting this approach. :^) 2020-06-21 13:14:02 +00:00			`JS_OBJECT(StringConstructor, NativeFunction);`
LibGC+Everywhere: Factor out a LibGC from LibJS Resulting in a massive rename across almost everywhere! Alongside the namespace change, we now have the following names: * JS::NonnullGCPtr -> GC::Ref * JS::GCPtr -> GC::Ptr * JS::HeapFunction -> GC::Function * JS::CellImpl -> GC::Cell * JS::Handle -> GC::Root 2024-11-14 15:01:23 +00:00			`GC_DECLARE_ALLOCATOR(StringConstructor);`

Libraries: Use default constructors/destructors in LibJS https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#cother-other-default-operation-rules "The compiler is more likely to get the default semantics right and you cannot implement these functions better than the compiler." 2022-03-14 16:25:06 +00:00			`virtual ~StringConstructor() override = default;`

LibJS: Convert NativeFunction::{call,construct}() to ThrowCompletionOr Both at the same time because many of them call construct() in call() and I'm not keen on adding a bunch of temporary plumbing to turn exceptions into throw completions. Also changes the return value of construct() to Object* instead of Value as it always needs to return an object; allowing an arbitrary Value is a massive foot gun. 2021-10-20 20:16:30 +00:00			`virtual ThrowCompletionOr<Value> call() override;`
