Andreas Kling	1382dbc5e1	LibJS: Add basic support for (scoped) variables ... It's now possible to assign expressions to variables. The variables are put into the current scope of the interpreter. Variable lookup follows the scope chain, ending in the global object.	2020-03-09 21:49:20 +01:00
Andreas Kling	63e4b744ed	LibJS: Add a basic mark&sweep garbage collector :^) ... Objects can now be allocated via the interpreter's heap. Objects that are allocated in this way will need to be provably reachable from at least one of the known object graph roots. The roots are currently determined by Heap::collect_roots(). Anything that wants be collectable garbage should inherit from Cell, the fundamental atom of the GC heap. This is pretty neat! :^)	2020-03-08 19:23:58 +01:00
Andreas Kling	f5476be702	LibJS: Start building a JavaScript engine for SerenityOS :^) ... I always tell people to start building things by working on the thing that seems the most interesting right now. The most interesting thing here was an AST + simple interpreter, so that's where we start! There is no lexer or parser yet, we build an AST directly and then execute it in the interpreter, producing a return value. This seems like the start of something interesting. :^)	2020-03-07 19:42:11 +01:00
