The output is exactly the same as in the Sorting based on the different values section before. As a first argument, you pass the array to sort and the second one is an array of object properties that we want to sort by (in the example below – sort first by breed, then by name if...
This example is really nothing special. You could achieve this with a native sorting algorithm in JavaScript, but I wanted to show how you can do it with the lodash orderBy function. This will sort the items array in ascending order based on the top level location property. ...
Another way to sort with language-sensitive string comparison is to useIntl.Collator. Using this approach, you use theIntl.Collatorconstructor and create a collator object that will be used in yourcompareFunction. The collator has a compare method that can be leveraged inside of the Array's sor...
