Then, run `rake test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment. 34 | 35 | To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org). 36 | 37 | ## Thanks 38 | 39 | Thanks to David Haney for excellent blog post on dependency management in nodejs 40 | http://www.haneycodes.net/npm-left-pad-have-we-forgotten-how-to-program/ 41 | 42 | Thanks also to Phil Nash for pointing out the lack of gems in the Ruby ecosystem 43 | at Bath Ruby 2016. 44 | 45 | ## Contributing 46 | 47 | Bug reports and pull requests are welcome on GitHub at https://github.com/[USERNAME]/is_array.
