Polly.JS vs Underscore: What are the differences?
Developers describe Polly.JS as "Record, replay, and stub HTTP interactions". Polly.JS is a standalone, framework-agnostic JavaScript library that enables recording, replaying, and stubbing HTTP interactions Polly taps into native browser APIs to mock requests and responses with little to no configuration while giving you the ability to take full control of each request with a simple, powerful, and intuitive API.. 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.
Polly.JS and Underscore can be primarily classified as "Javascript Utilities & Libraries" tools.
Polly.JS and Underscore are both open source tools. Underscore with 24.6K GitHub stars and 5.41K forks on GitHub appears to be more popular than Polly.JS with 7.75K GitHub stars and 219 GitHub forks.
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.
