In my opinion, this tool has been very helpful for me in terms of web development because it’s an easy way to get started using javascript at all which makes us more flexible since we can take things from other languages like Ruby or Python if needed. The only thing I don't really love about underscore js is how difficult its documentation is compared with jQuery docs. But overall I think its still better than most libraries out there. It's great because you can mix multiple types of Javascript together easily. For example, your backend code written in nodejs will be easier to integrate into the front end code written in react. As well as making our life easier by providing tools such as templates and autocomplete features.
