Dig(1, 0, 2) are safer versions of: hash_variable:foo:bar:baz array_variable102 The safe navigation operator will raise an error if a requested method, key, or index is not available; unlike the technique of using try for this purpose, which will return nil. Open-ended range creation, boolean flip-flop Binary 12 N/A?: A?B:C evaluates to B if A is true, or C if A is false Trinary 13 introduction Right rescue Modifier for catching exceptions.g. Is already used by convention for functions that return booleans. Not(a b) is false. Contents, operators edit, complete List and Precedence edit, operator, name/meaning, arguments, precedence. This technique is considered non-idiomatic and poor programming practice, because there are more explicit ways to force such a conversion (which is rarely needed to begin with). This will print the two lines "kiwi" and "kiwi told you so! Example: a nil b "foo" c a b # c is set to "foo" it's the same as saying c (a b) c a or b # c is set to nil it's the same as saying (c a) b which is not what you.
