TC39 investigated adding a method named "contains" to Array.prototype be we discovered that it cause web breakage: https://github.com/tc39/Array.prototype.includes#status . Instead a method called "includes" is on track to be added.

"items" is a possibility, but past experience suggests that there is a fair chance it would cause problems.
