Quick way of checking if object is in a list without a For Loop

Help and Feedback Scripting Support
#1

The title says it all. Is there a specific function I can use (that returns a boolean) to find if an object is within a list?

#2

Like table.find()?

example:

local t = {'ok', 'yes', 3}

print(table.find(t, 'yes')) -- 2, the index for that value

also if you want a bool

local function tobool(a)
  return not not a
end
