Functions for working with homogeneous JavaScript objects from PureScript. Similar to using Map String a
but simply reusing JavaScript objects.
spago install foreign-object
example = do let -- make an empty Object empty = FO.empty -- insert to an empty Object inserted = FO.insert "a" 1 empty -- or: use the singleton function -- singleton FO.singleton "a" 1 -- lookup values for existing in the Object as a result of Maybe let lookup = FO.lookup "a" inserted Assert.assertEqual { actual: lookup, expected: Just 1 } -- delete a value from an Object let deleted = FO.delete "a" inserted Assert.assertEqual { actual: deleted, expected: FO.empty } let -- convert homogeneous records to Object converted = FO.fromHomogeneous { a: 1, b: 2, c: 3} -- check that the converted is equal to a regularly built Object built = FO.empty # FO.insert "a" 1 # FO.insert "b" 2 # FO.insert "c" 3 Assert.assertEqual { actual: converted, expected: built }
