const
Describe the bug:
object extraction of a const variable errors at runtime
Config and Small code sample
Config:
{ compact: true, identifierGenerator: 'randomized', objectExtraction: true, target: 'browser', }
Code:
const obj = {prop: 0}; obj.prop = 1; console.log(obj.prop);
Expected behavior
The program should output 1
1
Actual behavior
TypeError: Assignment to constant variable.
obfuscated code:
const obj_prop=0;!(obj_prop=1,console['log'](obj_prop))
Additional context
an easy fix would probably be to convert the declaration to let or var

Great find, will fix this for next release.
Sorry, something went wrong.

just found an edge case: const can only be safely converted to let instead of var because of closures:
let
var
for (let i = 0; i < 3; i++) { const obj = { prop: i }; setTimeout(() => { console.log(obj.prop); // outputs 0, 1, 2 }, 100); }
after obfuscation: 2, 2, 2
2, 2, 2
I will get to work on this
