Blockly vs Underscore: What are the differences?

Introduction

This markdown code provides key differences between Blockly and Underscore.

1. Purpose: Blockly is a visual programming language that allows users to create programs by manipulating graphical blocks. It is primarily designed for beginners and educators to learn programming concepts through a visual interface. On the other hand, Underscore is a utility library that provides a set of functions to manipulate and operate on arrays, objects, and other data types in JavaScript. It is aimed at enhancing the functional programming capabilities of JavaScript developers.
2. Programming Paradigm: Blockly follows a block-based programming paradigm where users connect programming blocks together to create a program. It provides a drag-and-drop interface that allows for easy arrangement and organization of the blocks. In contrast, Underscore promotes a functional programming paradigm where functions are used to transform and manipulate data. It emphasizes immutability and encourages the use of functional programming concepts like map, reduce, filter, etc.
3. Learning Curve: Blockly is designed to be user-friendly and beginner-friendly, making it easier for novices to learn programming concepts. Its visual interface, block-based approach, and intuitive design make it accessible to a wide range of users. Underscore, on the other hand, requires a solid understanding of JavaScript and functional programming concepts. It may have a steeper learning curve for beginners who are not familiar with JavaScript.
4. Usage: Blockly is commonly used in educational settings, coding bootcamps, and online learning platforms to teach programming concepts and logic. It provides a fun and interactive way for learners to understand programming principles. Underscore, on the other hand, is widely used in JavaScript development projects where functional programming concepts are employed. It provides a set of powerful utility functions that simplify common programming tasks.
5. Extensibility: Blockly allows for the creation of custom blocks and extensions, enabling users to extend its functionality and adapt it to specific use cases. This extensibility allows for the creation of domain-specific languages and tailored programming environments. Underscore, on the other hand, is a standalone utility library that does not have an extensibility mechanism built-in. It provides a fixed set of functions that can be used out-of-the-box.
6. Dependencies: Blockly is a standalone library that does not have any external dependencies. It can be included in web applications without requiring additional libraries. Underscore, however, is built on top of the JavaScript language and requires JavaScript as a dependency. It needs to be included as a separate library in web applications.

In Summary, Blockly is a visual programming language designed for beginners and educators, featuring a block-based programming paradigm and a user-friendly interface. Underscore, on the other hand, is a utility library that enhances the functional programming capabilities of JavaScript developers, focusing on arrays, objects, and data manipulation.

Advice on Underscore, Blockly

Abigail

Dec 6, 2019

Decided

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.

What are some alternatives to Underscore, Blockly?

Deno

It is a secure runtime for JavaScript and TypeScript built with V8, Rust, and Tokio.

Chart.js

Visualize your data in 6 different ways. Each of them animated, with a load of customisation options and interactivity extensions.

Immutable.js

Immutable provides Persistent Immutable List, Stack, Map, OrderedMap, Set, OrderedSet and Record. They are highly efficient on modern JavaScript VMs by using structural sharing via hash maps tries and vector tries as popularized by Clojure and Scala, minimizing the need to copy or cache data.

Lodash

A JavaScript utility library delivering consistency, modularity, performance, & extras. It provides utility functions for common programming tasks using the functional programming paradigm.

Ramda

It emphasizes a purer functional style. Immutability and side-effect free functions are at the heart of its design philosophy. This can help you get the job done with simple, elegant code.

Vue CLI

Vue CLI aims to be the standard tooling baseline for the Vue ecosystem. It ensures the various build tools work smoothly together with sensible defaults so you can focus on writing your app instead of spending days wrangling with config.

Luxon

It is a library that makes it easier to work with dates and times in Javascript. If you want, add and subtract them, format and parse them, ask them hard questions, and so on, it provides a much easier and comprehensive interface than the native types it wraps.

Prepack

Prepack is a partial evaluator for JavaScript. Prepack rewrites a JavaScript bundle, resulting in JavaScript code that executes more efficiently. For initialization-heavy code, Prepack works best in an environment where JavaScript parsing is effectively cached.

Cesium

it is used to create the leading web-based globe and map for visualizing dynamic data. We strive for the best possible performance, precision, visual quality, ease of use, platform support, and content.

Factor

It is an extension-focused and universal Vue.js platform for professional front-end developers. It will help you launch apps that impress and astonish your clients and colleagues. No more re-inventing the wheel, or rewriting and refactoring where it's unneeded.
