Ext JS vs Underscore: What are the differences?
What is Ext JS? Create data-intensive HTML5 applications using JavaScript. Helps build data-intensive, cross-platform web apps for desktops, tablets, and smartphones. Enables organizations to handle millions of records and provides out-of-the-box functionality such as sorting, grouping, column locking, and sum.
What is Underscore? JavaScript's utility _ belt. A JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects.
Ext JS and Underscore belong to "Javascript Utilities & Libraries" category of the tech stack.
Underscore is an open source tool with 24.7K GitHub stars and 5.41K GitHub forks. Here's a link to Underscore's open source repository on GitHub.
According to the StackShare community, Underscore has a broader approval, being mentioned in 1047 company stacks & 76 developers stacks; compared to Ext JS, which is listed in 12 company stacks and 7 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.
