How to do a case insensitive sorting on a collection using Lodash orderBy with JavaScript?

To do a case insensitive sorting on a collection using Lodash orderBy with JavaScript, we can convert all the values to lower case before we compare them with orderBy.

For instance, we write

const users = [
  { name: "A", age: 48 },
  { name: "B", age: 34 },
  { name: "b", age: 40 },
  { name: "a", age: 36 },
];

const sortedUsers = _.orderBy(
  users,
  [(user) => user.name.toLowerCase()],
  ["desc"]
);
console.log(sortedUsers);

to call orderBy with the users array, an array with a function that convert each object’s name property to lower case, and an array with the order that we want to sort by.

We convert each name property to lower case with the toLowerCase method.

A new array with the sorted values is returned.
