Sugar is a JavaScript utility library that extends native objects like Arrays, Strings, and Dates with helpful methods for common tasks. Developers use it to write more concise code when manipulating data and working with built-in types, either through polyfills that add methods directly to native prototypes or through standalone utilities. It's useful for reducing boilerplate code across projects, though developers should consider whether extending native objects fits their coding standards.
