javascript - Does nodejs/V8 store compiled machine code anywhere on disk? -

edit: @dystroy notes below, node uses machine code directly, not bytecode.

i lot of python coding, , there's bytecode lying around in .pyc files.

i wondering if node stores machine code in similar files, eg make sense keep machine code representation around on disk , re-use if file's source unchanged.

if so, node/v8 store machine code?

edit 2: @dystroy mentions below dupe of how can see machine code generated v8?

v8 introduced bytecode interpreter, ignition, in 2016. can print bytecode --print-bytecode (node 8.3 , newer).

$ node --print-bytecode incrementx.js -e 'function incrementx(obj) {return 1 + obj.x;} incrementx({x: 42});` ... [generating bytecode function: incrementx] parameter count 2 frame size 8   12 e> 0x2ddf8802cf6e @    stackcheck   19 s> 0x2ddf8802cf6f @    ldasmi [1]         0x2ddf8802cf71 @    star r0   34 e> 0x2ddf8802cf73 @    ldanamedproperty a0, [0], [4]   28 e> 0x2ddf8802cf77 @    add r0, [6]   36 s> 0x2ddf8802cf7a @    return constant pool (size = 1) 0x2ddf8802cf21: [fixedarray] in oldspace  - map = 0x2ddfb2d02309 <map(holey_elements)>  - length: 1            0: 0x2ddf8db91611 <string[1]: x> handler table (size = 16) 

see understanding v8's bytecode.

to see machine code, use --print-opt-code --code-comments.
