What are the advantages of using Underscore.js?

The advantages of using Underscore.js are its extensive utility functions that simplify data manipulation in JavaScript. Underscore.js can help reduce tedious, longer code in JavaScript with its mappings, filtering, sorting, and reduction functions, making the code more readable and maintainable. It offers a consistent syntax across browsers, hence improving cross-browser compatibility. The fact that it does a lot of common tasks with fewer lines of code makes it productive for projects in which functional programming along with clean code structure is required. It’s lightweight, and including it into projects doesn’t cause noticeable performance overhead.
