arrange the elements in an array list alphabetically by name using the lodash library

Is there a way to alphabetically sort the names in an array list using JavaScript? I attempted to achieve this with the following code:

const sample = [
    {
        name: "AddMain",
        mesg: "test000"
    },
    {
        name: "Ballside",
        mesg: "test004545"
    },
    {
        name: "TestMain",
        mesg: "test00"
    },
    {
        name: "ball",
        mesg: "test004545"
    },
    {
        name: "Main",
        mesg: "test004545"
    },
    {
        name: "alliswell",
        mesg: "test004545"
    }
]

sample.sort(sortBy('name', false, function(a){return a.toUpperCase()}));

Unfortunately, the sorting doesn't seem to work correctly. I am using lodash for the sortBy function and if there is a better way to do this with lodash or any other method, that would be great.

DEMO

const exampleSet = [
    {
        title: "Apple",
        message: "demo001"
    },
    {
        title: "Banana",
        message: "demo002"
    },
    {
        title: "Carrot",
        message: "demo003"
    },
    {
        title: "Daisy",
        message: "demo004"
    },
    {
        title: "Eagle",
        message: "demo005"
    }
];


var elements =_.orderBy(exampleSet, [item => item.title.toLowerCase()], ['asc']);
 
console.log(elements);

Answer №2

As per the documentation provided by lodash, the API for sortBy is outlined as follows:

_.sortBy(collection, [iteratees=[_.identity]])

In this scenario, the collection refers to your array named sample, and the [iteratees=[_.identity]] should consist of a function or an array that specifies the key for sorting.

Based on your requirement, you may want to use:

_.sortBy(sample, ['name']);

OR

_.sortBy(sample, function(o){return o.name;}]);

Answer №3

Learn about _.sortBy() function

To implement this function, your code should resemble the following example:

DEMO

const sample = [{
  name: "AddMain",
  mesg: "test000"
}, {
  name: "Ballside",
  mesg: "test004545"
}, {
  name: "TestMain",
  mesg: "test00"
}, {
  name: "ball",
  mesg: "test004545"
}, {
  name: "Main",
  mesg: "test004545"
}, {
  name: "alliswell",
  mesg: "test004545"
}];

let result = _.sortBy(sample, ({name}) => name.toLowerCase());

console.log(result);
.as-console-wrapper {max-height: 100% !important;top: 0;}
<script src="//lodash.com/vendor/cdn.jsdelivr.net/npm/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="402c2f2421332800746e71776e7170">[email protected]</a>/lodash.min.js"></script>

Answer №4

const items = [
    {
        label: "Apple",
        price: "$1.00"
    },
    {
        label: "Banana",
        price: "$0.50"
    },
    {
        label: "Orange",
        price: "$0.75"
    }
]

var sortedItems = items.slice().sort((a,b) => a.label.localeCompare(b.label, undefined, {numeric: true}));
console.log(sortedItems);

const spaceCrew = [
  { name: 'Jean-Luc Picard', age: 59 },
  { name: 'William Riker', age: 29 },
  { name: 'Deanna Troi', age: 28 },
  { name: 'Worf', age: 24 }
];

// Organize space crew members by their age
const organizedSpaceCrew = _.sortBy(spaceCrew, 'age');

console.log(organizedSpaceCrew);

organizedSpaceCrew[0].name; // Worf
organizedSpaceCrew[1].name; // Deanna Troi
organizedSpaceCrew[2].name; // William Riker
organizedSpaceCrew[3].name; // Jean-Luc Picard
