giles	e0531d730c	js-on-sx: drop top-level (define NaN) / (define Infinity) — SX parses those as numbers	2026-04-23 20:45:12 +00:00
giles	608a5088a4	js-on-sx: expanded Math + Number globals ... Math gains sqrt/pow/trunc/sign/cbrt/hypot plus LN2/LN10/LOG2E/ LOG10E/SQRT2/SQRT1_2 constants and full-precision PI/E. Number global: isFinite/isNaN/isInteger/isSafeInteger plus MAX_VALUE/MIN_VALUE/MAX_SAFE_INTEGER/MIN_SAFE_INTEGER/EPSILON/ POSITIVE_INFINITY/NEGATIVE_INFINITY/NaN. Global isFinite, isNaN, Infinity, NaN. Wired into js-global. 329/331 unit (+21), 148/148 slice unchanged.	2026-04-23 20:42:57 +00:00
giles	ce46420c2e	js-on-sx: regex literal lex+parse+transpile+runtime stub ... Lexer: js-regex-context? disambiguates / based on prior token; read-regex handles [...] classes and \ escapes. Emits {:type "regex" :value {:pattern :flags}}. Parser: new primary branch → (js-regex pat flags). Transpile: (js-regex-new pat flags). Runtime: js-regex? predicate, js-regex-new builds tagged dict with source/flags/global/ignoreCase/multiline/sticky/unicode/dotAll/ hasIndices/lastIndex. js-regex-invoke-method dispatches .test/.exec/ .toString. js-invoke-method detects regex receivers. Stub engine uses js-string-index-of; __js_regex_platform__ + override! let a real engine plug in later. Runner: repeatable --filter flags (OR'd). 308/310 unit (+30 regex tests), 148/148 slice unchanged.	2026-04-23 20:27:19 +00:00
giles	9e568ad886	js-on-sx: baseline commit (278/280 unit, 148/148 slice, runner stub) ... Initial commit of the lib/js/ tree and plans/ directory. A previous session left template-string work in progress — 278/280 unit tests pass (2 failing: tpl part-count off-by-one, escaped-backtick ident lookup). test262-runner.py and scoreboard are placeholders (0/8 with 7 timeouts); fixing the runner is the next queue item.	2026-04-23 19:42:16 +00:00
