fail to run js code

Thanks for your work!

When I tried to run a piece of code, I got SyntaxError: Identifier 'a' has already been declared.

And I tried all ecmaVer.

Here is the code: jsbin

I’m so sorry but I was trying to solve obfuscated code with sval, I do not have the raw source code.

At least you can try to pretty-print it…

The problem is in the _k function:

var variables should be able to be redefined. let and const are the ones not allowed to be redefined. I don’t know if that’s something about strict mode also.

Maybe there’s a chance to catch eval calls and run them though sval.
