Groovy not in collection

Question

The groovy way to see if something is in a list is to use \"in\"

   if(\'b\' in [\'a\',\'b\',\'c\'])

However how do you nicely see if something

Answer 1

More readable, I'm not sure:

assert ['a','b','c'].any{it == 'b'}
assert ['a','b','c'].every{it != 'g'}

For your example:

if (['a','b','c'].every{it != 'g'})

A few months ago, I suggested a new operator overloading ! (not operator). Now, maybe you can use any odd number of exclamations ;)

if(!!!('g' in ['a','b','c']))
