• Optimize hot paths: ConstantProp 30x faster, ExpressionSimplifier 2.2x faster on large files
• 9% faster end-to-end vs main across 525-file benchmark (20.3s → 18.5s)

0.1.4

Wide range of optimizations, recursion guards and style improvements

0.1.3

What's Changed

• Add pure Python JSFuck, JJEncode, and AAEncode decoders by @itamarga in #8

0.1.2

What's Changed

0.1.2

Pure Python

PyJSClear no longer requires Node.js. The JSFuck and JJEncode transforms
that depended on Node.js eval have been removed, and the eval_unpack
fallback now uses only the built-in Python Dean Edwards unpacker.

New transforms (22)

Significantly improved deobfuscation for esbuild-bundled and complex
obfuscated JavaScript:

• String decoding: XOR byte-array decoder, class-based lookup table decoder
• Constant resolution: member chain resolver (A.B.C → literal), class
  static constant/method inlining, TypeScript enum inlining, global alias
  inlining (var X = JSON → JSON), hex numeric normalization
• Modern JS recovery: optional chaining (?.), nullish coalescing (??),
  optional catch binding, let/var → const
• Dead code elimination: dead branches in logical expressions, dead class
  properties, dead object properties, dead expressions, unreachable code
  after return/throw, noop method call removal, empty if removal
• Cleanup: else-if flattening, trailing return removal, return undefined
  simplification, single-use variable inlining, require polyfill inlining,
  (0, expr)() comma-operator simplification
• Static evaluation: Buffer.from([...]).toString(encoding), (N).toString()

Variable renaming

New post-pass replaces _0x-prefixed identifiers with readable names using
heuristic analysis: require() module names, constructor types, loop counters,
and usage-based method inference.

Bug fixes

• MemberChainResolver: fixed stale placeholder '' inlining through 2-level
  alias chains (~75 false empty-string inlinings eliminated)
• unused_vars: check side effects in ArrayExpression/ObjectExpression children
• object_simplifier: only report changes when replacement succeeds
• string_revealer: report changes after sequence expression mutations
• Scope analysis: handle class expressions, rest params, and catch clauses
• Guards against proxy function inliner blowup on deeply nested helpers

Infrastructure

• Parallel CI test execution (pytest-xdist)
• Snapshot regression testing with golden file
• 1705 tests, 65 regression tests across 25 samples
