UglifyJS vs Underscore: What are the differences?
Developers describe UglifyJS as "JavaScript parser / mangler / compressor / beautifier library for NodeJS". This package implements a general-purpose JavaScript parser/compressor/beautifier toolkit. It is developed on NodeJS, but it should work on any JavaScript platform supporting the CommonJS module system (and if your platform of choice doesn’t support CommonJS, you can easily implement it, or discard the exports.* lines from UglifyJS sources). On the other hand, Underscore is detailed as "JavaScript's utility _ belt". A JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects.
UglifyJS and Underscore belong to "Javascript Utilities & Libraries" category of the tech stack.
UglifyJS and Underscore are both open source tools. It seems that Underscore with 24.6K GitHub stars and 5.41K forks on GitHub has more adoption than UglifyJS with 8.12K GitHub stars and 761 GitHub forks.
Pinterest, reddit, and LinkedIn are some of the popular companies that use Underscore, whereas UglifyJS is used by bitHOUSEweb S.r.l., Atbox, and Glitch. Underscore has a broader approval, being mentioned in 1047 company stacks & 76 developers stacks; compared to UglifyJS, which is listed in 7 company stacks and 13 developer stacks.
Fast Healthcare Interoperability Resources (FHIR) provides standard data objects in JSON format for the healthcare industry. Since JSON objects are hierarchical and tree-like, we had a need to defensively 'pluck' fields from our JSON objects and do lots of mapping. We tried jQuery and Underscore and a few other technologies like FHIRPath; but Lodash has been the most well supported, works in the most contexts, has the cleanest syntax, etc. We particularly like the ES6 version of Lodash, where we can import
the method names directly, without resorting to * or _ syntax. We got hooked on the 'get' function to defensively pluck fields from objects without crashing our user interface, and have found countless uses for the other lodash functions throughout our apps.
Lodash is great for developing and optimizing algorithms.
