Underscore vs Blockly: What are the differences?

Underscore: JavaScript's utility _ belt. A JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects; Blockly: A library that adds a visual code editor to web and mobile apps. It is a client-side library for the programming language JavaScript for creating block-based visual programming languages and editors. It is a project of Google and is free and open-source software.

Underscore and Blockly can be categorized as "Javascript Utilities & Libraries" tools.

Underscore and Blockly are both open source tools. Underscore with 24.9K GitHub stars and 5.43K forks on GitHub appears to be more popular than Blockly with 6.84K GitHub stars and 2.37K GitHub forks.

Decisions about Blockly and Underscore

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.
