dofile

Reads a file from the workspace, compiles it with loadstring, and immediately executes the resulting closureClosureA function value that captures its lexical environment. In Luau, closures come in two types: LClosure (Luau bytecode + Proto + upvalues) and CClosure (native C function pointer + upvalues).. Equivalent to:

local fn = loadstring(readfile(path))
return fn()

Unlike loadfile, this executes the code immediately rather than returning a callable function. The environment is the caller's global environmentGlobal environment (genv)The executor's global environment table — the _G-equivalent for executor-loaded scripts. Functions set here (via getgenv()) are accessible from any executor script but invisible to game scripts.. Throws on file-not-found or compilation errors.
