loadstring

Unsafe by design

Compiles the given string, and returns it runnable in a function. The environment must become unsafe after this function is called due to it allowing the modification of globals uncontrollably (see setfenv/getfenv documentation).

Should error when compilation fails

This function should return nil and an error message if the provided code fails to compile.

loadstring compiles a string of Luau code and returns it as a runnable function. If the code has errors, nil is returned and an error message is output.

function loadstring<A...>(source: string, chunkname: string?): (((A...) -> any) | nil, string?)

Parameters

Parameter	Description
source	The source code string to compile.
chunkname?	Custom chunk name.
