How to Sort an Array of JavaScript Objects by Attribute Name?

Sorting an Array of Objects by Attribute Name Using JavaScript

In JavaScript, arrays of objects can be sorted based on specific attributes. This process becomes necessary when dealing with complex data structures where maintaining order is crucial.

Question:

How can an array of objects be sorted in ascending order of an attribute (e.g., "name")?

Answer:

To sort an array of objects based on an attribute name, a custom comparison function can be defined and passed to the sort() method. Here's an example:

// Custom comparison function
function SortByName(a, b){
  var aName = a.name.toLowerCase();
  var bName = b.name.toLowerCase(); 
  return ((aName < bName) ? -1 : ((aName > bName) ? 1 : 0));
}

// Sort the array
array.sort(SortByName);

In this example, the SortByName function compares the lowercase versions of the "name" property for each two objects (a and b) in the array. If the result is less than 0, object a is placed before object b, if it's greater than 0, b is placed before a, and if it's 0, the order remains unchanged.

By passing this function to sort(), the array is sorted in ascending order of the "name" attribute. The lowercase comparison ensures that names with different cases are treated equally.
