Decompile Electron 18 .jsc Files
Electron 18 runs on the V8 10.0 line. JSC Decompiler reads the V8 build straight from the bytecode header and turns compiled .jsc files back into readable JavaScript — no matching runtime required.
Bytecode fingerprint
Every .jsc file opens with a 4-byte little-endian magic header that identifies the V8 code-cache format. Electron 18 files sit on the V8 10.0 line, paired with Node.js 16.

Upload at jscdecompiler.com

Auto-detect the version
JSC Decompiler reads the magic header and selects the V8 10.0 deserializer automatically — you never pick a version by hand.

Electron 18 version notes
- Electron 18 runs Chromium 100 on the V8 10.0 line and bundles Node.js 16; its modules carry the 0xC0DE054D magic.
- It is the first Electron on the V8 10.x line, one major ahead of the Node 16 it bundles for the main process.
- Pointer compression is on, so the code-cache layout differs from a plain Node build of V8 10.0.
Electron 18 decompilation FAQ
What V8 version does Electron 18 use?
The V8 10.0 line (Chromium 100), magic 0xC0DE054D.
Does the bundled Node version match the renderer V8?
Not exactly — Electron 18 bundles Node 16 (V8 9.x) but its Chromium/V8 is 10.0. The decompiler keys off each file's own header.
