Example

In a game whose shop UI is a LocalScript, recover its hardcoded string literals even though Roblox stripped .Source on the client.

local target = game:GetService("Players").LocalPlayer.PlayerScripts:FindFirstChildOfClass("LocalScript")
local closure = getscriptclosure(target)
for i, k in ipairs(debug.getconstants(closure)) do
    print(`[{i}] {typeof(k)} {tostring(k)}`)
end

Roblox strips LocalScript.Source and ModuleScript.Source to empty strings on the client. getscriptclosure() paired with debug.getconstants() is the way around it - the returned closure carries the script’s bytecode, which debug reads directly.
