Bugs:
- modules: better error handling with cyclic module references
Misc ideas:
- use custom printf to avoid compatibility issues with floating point numbers
- consistent naming for preprocessor defines
- unify coding style and naming conventions
- use names from the ECMA spec in library implementation
- use byte code emitters with typed arguments (for clarity)
- use 2 bytecode DynBufs in JSFunctionDef, one for reading, one for writing
and use the same wrappers in all phases
- use more generic method for line numbers in resolve_variables and resolve_labels
- use custom timezone support to avoid C library compatibility issues
Memory:
- use memory pools for objects, etc?
- test border cases for max number of atoms, object properties, string length
- add emergency malloc mode for out of memory exceptions.
- test all DynBuf memory errors
- test all js_realloc memory errors
- improve JS_ComputeMemoryUsage() with more info
Built-in standard library:
- BSD sockets
- modules: use realpath in module name normalizer and put it in quickjs-libc
- modules: if no ".", use a well known module loading path ?
- get rid of __loadScript, use more common name
REPL:
- debugger
- readline: support MS Windows terminal
- readline: handle dynamic terminal resizing
- readline: handle double width unicode characters
- multiline editing
- runtime object and function inspectors
- interactive object browser
- use more generic approach to display evaluation results
- improve directive handling: dispatch, colorize, completion...
- save history
- close all predefined methods in repl.js and jscalc.js
Optimization ideas:
- 64-bit atoms in 64-bit mode ?
- 64-bit small bigint in 64-bit mode ?
- reuse stack slots for disjoint scopes, if strip
- add heuristic to avoid some cycles in closures
- small String (0-2 charcodes) with immediate storage
- perform static string concatenation at compile time
- optimize string concatenation with ropes or miniropes?
- add implicit numeric strings for Uint32 numbers?
- optimize `s += a + b`, `s += a.b` and similar simple expressions
- ensure string canonical representation and optimise comparisons and hashes?
- remove JSObject.first_weak_ref, use bit+context based hashed array for weak references
- property access optimization on the global object, functions,
prototypes and special non extensible objects.
- create object literals with the correct length by backpatching length argument
- remove redundant set_loc_uninitialized/check_uninitialized opcodes
- peephole optim: push_atom_value, to_propkey -> push_atom_value
- peephole optim: put_loc x, get_loc_check x -> set_loc x
- convert slow array to fast array when all properties != length are numeric
- optimize destructuring assignments for global and local variables
- implement some form of tail-call-optimization
- optimize OP_apply
- optimize f(...b)
