    Filter an Array with Truthy Values

    Shane OsbourneShane Osbourne

    Array filter creates a new array with all elements that pass the test implemented by the provided function. In this lesson we discuss how only a truthy or falsey value is required as the return value to the function, which in turns allows us to be creative in how we perform the filter. We end the lesson by looking at an example showing how chaining multiple array methods together can lead to very nice, declarative code.
