# ⚡️ QuickJS - A mighty JavaScript engine
|
||||||
|
|
||||||
|
Friendly [QuickJS](https://bellard.org/quickjs) fork focused on reigniting the project.
|
||||||
|
|
||||||
|
🚧 Work in progress.

|

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)
|
