A pangram is a sentence that contains all the letters of the English alphabet at least once.
For example: ''The quick brown fox jumps over the lazy dog''.
;Task:
Write a function or method to check a sentence to see if it is a [[wp:Pangram|pangram]] (or not) and show its use.
;Related tasks:

===AppleScriptObjC===
Out of the box, AppleScript lacks many library basics – no regex, no higher order functions, not even string functions for mapping to upper or lower case.
From OSX 10.10 onwards, we can, however, use ObjC functions from AppleScript by importing the Foundation framework. We do this below to get a toLowerCase() function. If we also add generic filter and map functions, we can write and test a simple isPangram() function as follows:
<syntaxhighlight lang="applescript">use framework "Foundation" -- ( for case conversion function )
--------------------- PANGRAM CHECKER --------------------
-- isPangram :: String -> Bool
on isPangram(s)
script charUnUsed
property lowerCaseString : my toLower(s)
on |λ|(c)
lowerCaseString does not contain c
end |λ|
end script
0 = length of filter(charUnUsed, ¬
"abcdefghijklmnopqrstuvwxyz")
end isPangram
--------------------------- TEST -------------------------
on run
map(isPangram, {¬
"is this a pangram", ¬
"The quick brown fox jumps over the lazy dog"})
--> {false, true}
end run
-------------------- GENERIC FUNCTIONS -------------------
-- filter :: (a -> Bool) -> [a] -> [a]
on filter(f, xs)
tell mReturn(f)
set lst to {}
set lng to length of xs
repeat with i from 1 to lng
set v to item i of xs
if |λ|(v, i, xs) then set end of lst to v
end repeat
return lst
end tell
end filter
-- map :: (a -> b) -> [a] -> [b]
on map(f, xs)
tell mReturn(f)
set lng to length of xs
set lst to {}
repeat with i from 1 to lng
set end of lst to |λ|(item i of xs, i, xs)
end repeat
return lst
end tell
end map
-- Lift 2nd class handler function into
