Prepack vs Underscore: What are the differences?

What is Prepack? A tool for making JavaScript code run faster (by Facebook). 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.

What is Underscore? JavaScript's utility _ belt. A JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects.

Prepack and Underscore can be primarily classified as "Javascript Utilities & Libraries" tools.

Prepack and Underscore are both open source tools. It seems that Underscore with 24.6K GitHub stars and 5.41K forks on GitHub has more adoption than Prepack with 13.7K GitHub stars and 463 GitHub forks.
