JavaScript Library & Framework
6,289 of the 1,000,000 top sites in our Tranco top-1M census run Underscore.js (0.6%). A utility JavaScript library providing functional helper methods for working with arrays, objects, and functions. Detection is homepage-level HTML/header fingerprinting, so a site can run Underscore.js on other pages without it showing here.
