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.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eThis book explores how to use Underscore.js to power your code and understand modern JavaScript development concepts while applying a lightweight and efficient workflow to build applications.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eThe book starts with an incremental Underscore.js introduction by exploring key JavaScript concepts. You will then explore the basic features of Underscore.js in action and establish a lightweight development workflow that allows the provided examples to be guided by tests. The book then covers the functionality of Underscore.js with in-depth examples and explanations for understanding and applying the Underscore.js API. You'll also learn how to use Underscore.js as a base for your own modules and libraries within an object-oriented or functional programming style, and will be able to explore Underscore.js use cases in different environments.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eEventually, you'll learn about libraries that are closely related with Underscore.js, how to share code between client and server, and how to prepare for the upcoming JavaScript standard ECMAScript 6.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStyle and approach\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eThis book takes an example-driven approach to describing some of the essential JavaScript concepts and practices that are useful for building sustainable applications.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Packt Publishing","offers":[{"title":"Default Title","offer_id":47137036861680,"sku":"9781784397067","price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781784397067_p0.jpg?v=1763728308","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781784397067","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
