In Detail

Underscore.js is one of the most popular modern JavaScript libraries used for functional programming. It can be used as a base for building complex JavaScript applications in a sustainable manner and for building other JavaScript libraries. It embraces functional programming principles but is not opinionated and can be used with imperative, object-oriented, functional, or other programming styles.

This book explores how to use Underscore.js to power your code and understand modern JavaScript development concepts while applying a lightweight and efficient worls,
