Chapter 3. Using Underscore.js with Arrays, Objects, and Functions

The previous chapter explored the functionality provided by Underscore.js for collections. This chapter will continue in the same vein and will further explore the specialized features that Underscore implements for:

  • Arrays

  • Objects

  • Functions

  • Utility functions

The chapter assumes that you are familiar with the JavaScript built-in data types.

The source code for the examples from this chapter is hosted online at https://github.com/popalexandruvasile/underscorejs-examples/tree/master/arrays-objects-functions, and you can execute the examples using Cloud9 IDE at the address https://ide.c9.io/alexpop/underscorejs-examples from the arrays-functions-objects folder.
