I want to find the length of the variable in the API, how do I do that?

If I have a local variable called xxx in an API called yyy is there a way I can pull xxx from the yyy API to a whole new program (lets say zzz)? Something like :

 if #yyy.xxx == 0 then print("No") else print("Yes") end 

string.len(xxx.yyy)
--or 
xxx.yyy:length() (?)

local w,h = term.getSize()

function CLocate(Cstring)
  term.clear()
  term.setCursorPos(w/2 - #Cstring/2,h/2)
  print(Cstring)
end

function prompt(string)
  CLocate(string)
  answer = read()
end
 

os.loadAPI("JS")
JS.prompt("What's up?")
if string.len(JS.answer) == 0 then
print("No")
elseif JS.answer == ("The sky.") then
print("That's an old one.")
elseif JS.answer == ("Not much.") then
print("Cool, me too.")
end
 

local w,h = term.getSize()
function CLocate(Cstring)
  term.clear()
  term.setCursorPos(w/2 - #Cstring/2,h/2)
  print(Cstring)
end
function prompt(string)
  CLocate(string)
  JS.answer = read()
end

1 more thing, string is an API. You are going to do bad overwriting standard API's.

> #("a string") == 8
true
