Since the following doesn't seem to do it:
_.all([true, true, true], true);
it returns: false?

Reset to default 36You should re-read the _.every(collection, [predicate=_.identity]) api doc of lodash. The issue with your code is the second param you are passing. Remove it and it works
> _.every([true, 'foo', 1])
true
> _.every([true, 'foo', 1, 0])
false
