Creating generic functions can make all the difference in the size and comprehensibility of our code. A generic function is useful in more than one context. It is loosely coupled to the application. That's what higher-level building blocks are all about; whether we're using a functional programming model, a more object-oriented approach, or a hybrid of the two, the key lies in generic components. As with most other aspects of programming, Lo-Dash provides many avenues to construct generic components. We'll address many of them throughout the course of this chapter. Let's start off by looking at functions that aren't so generic and how they compare with their more fluid cousins.

var collection = [
    { name: 'Ronnie', age: 43 },
    { name:...
