JavaScript Array of Objects Sorting: How to Sort by a Specific Object Property

hectorsalamanca — Wed, 13 Dec 2023 14:17:52 GMT

I have an array of objects in JavaScript, and I want to sort them based on a specific property of the objects. For example, I have an array of books, and each book object has properties like 'title', 'author', and 'publicationYear'. How can I sort this array of book objects alphabetically by the 'title' property?

Here's a simplified version of the array:

This array should be sorted ascendingly using the 'title' parameter. I attempted to discover the answer by going to several sites, but I was unable to locate the solution. Could you supply a JavaScript code sample that explains how to do this sorting and explains any key ideas or functions utilized in the code? I appreciate your help.

Hi @hectorsalamanca , take a look at this website for the full explanation but below is a code snippet that should sort your array of objects.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort#sorting_array_of_objects

// sort by title books.sort((a, b) => { const titleA = a.title.toUpperCase(); // ignore upper and lowercase const titleB = b.title.toUpperCase(); // ignore upper and lowercase if (titleA < titleB) { return -1; } if (titleA > titleB) { return 1; } // names must be equal return 0; });

You have to use the array.sort method, using a compare function to define the sort order. Take a look at this section of the documentation that explains different ways of sorting arrays of objects. In this example, a simpler sort function uses the locateCompare method to return the sorted titles.
