Lodash vs PDF.js: What are the differences?
Introduction:
Lodash and PDF.js are two widely used libraries in web development, each serving different purposes. Understanding the key differences between these two libraries is crucial in choosing the right tool for specific tasks.
Functionality: Lodash is a utility library that provides a wide range of functions to manipulate and work with arrays, objects, and other data structures in JavaScript. On the other hand, PDF.js is a library specifically designed for working with PDF files in web applications, allowing users to render, manipulate, and interact with PDF documents directly in the browser.
Use Cases: Lodash is often used for general-purpose data manipulation tasks, such as filtering, sorting, and transforming data, while PDF.js is primarily used for tasks related to displaying and working with PDF files, such as viewing, searching, and extracting text from PDF documents.
Dependencies: Lodash is a standalone library that can be easily included in a project using a simple script tag or through package managers like npm or yarn. PDF.js, on the other hand, has dependencies on other libraries such as Mozilla's PDFium and can be more challenging to integrate into a project due to its size and complexity.
Community Support: Lodash has a large and active community of developers contributing to its development and maintenance, ensuring regular updates and bug fixes. PDF.js, being developed by Mozilla, also has strong community support but may not be as actively maintained as Lodash.
In Summary, Lodash is a versatile utility library for data manipulation in JavaScript, while PDF.js is specifically tailored for working with PDF files in web applications, each serving distinct purposes in web development.
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.
