Using the Array Filter Method

Learning Goals

• Practice using filter() to return matching results

Introduction

We've all probably had the experience of filtering a selection of choices online. When shopping for clothing, we might have selected a single size so that we can consider only the search results we need. Or when ordering food online, we could have customized our results to only show restaurants currently open or offering delivery in our neighborhoods. Since it's such a common need for a user, it's also a common function for a web programmer to run. Fortunately for us, JavaScript provides a built-in filter() method.

Use filter() to Return Matching Results

We have an array of drivers with various information. We need to write functions using the filter() method so that PickMeUp Taxi service employees can easily query the data. Run the tests to see what conditions need to be met by each function before you start writing JavaScript code.

You'll be writing three functions:

• findMatching- This function takes an array of drivers' names and a string as arguments, and returns the matching list of drivers. The function should be case insensitive.

• fuzzyMatch - This function takes an array of drivers' names and a string as arguments for querying the array, and returns all drivers whose names begin with the provided letters.

• matchName - This function takes an array of driver objects and a string as arguments. Each driver object has two properties: name and hometown. The function should return each element whose name property matches the provided string argument.
