When it comes to Lodash Find vs Lodash Filter, ask yourself: “Do I need to find ONE thing in my array, or MULTIPLE things?”
Lodash is a library similar to jQuery, Tornis, and Pixelmatch. It must be loaded before you can use it. Lodash is a popular library with many great features that help with manipulating and iterating through objects, arrays, functions, and collections.
The Lodash .filter() method is very similar to the Lodash find method except that it allows you to find several items of the same type in a collection. The filter method returns an array of results.
Lodash Find vs Lodash Filter Examples
Let’s take a look at a few examples to help you see the difference. We have an array called cars that holds three objects. Each object is a vehicle that has three properties: name, maker, and issuv.
In Example 1, we want to find an object named Mustang. There are only a few names, and each name is different, so the Lodash find method is a perfect choice for this example. The find method returns the first Mustang that it sees, and console.log prints it to the screen.
In Example 2, we demonstrate a problem with the Lodash find method. In this case, we want to know which objects are SUVs. If we use the Lodash find method this time, it will return the object named EcoSport, and console.log will print it to the screen. It will not see that the CR-V is also an SUV because it stops when it finds a match. The same problem will occur if you inquire about which objects are made by Ford.
In Example 3, we demonstrate that to find multiple objects, we will need to use the Lodash filter method. This time we will try again to see which objects are SUVs, but this time we will use the Lodash filter method. The filter method will return an array containing every object that is an SUV. In this case, the result will be the EcoSport and the CR-V.
This method will also work correctly to find which vehicles are made by Ford.
