I like that it is easy to add new functionality or fix bugs without having to make major changes to our code base. We're able to deploy features quickly and iterate quicker than we used too in other languages (e.g., Python). It's also very helpful for people who have never worked with Javascript before because of its simplicity when compared to some similar frameworks out there. The documentation can be pretty lacking sometimes - so you will need experience working with javascript/front end development to get up-to speed fast. If you are building something from scratch then this isn't necessarily an issue but if your project has already been built using another framework then finding docs which help translate those concepts over into JS might take time. Our team uses iterative heavily to build products rapidly by continuously refining our frontend applications while keeping them as close to production quality as possible!
