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

// Sort characters by the `age` property
const sorted = _.sortBy(characters, 'age');

console.log(sorted);

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

_.sortBy()

Your code should be like:

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/[email protected]/lodash.min.js"></script>

    {

        mesg: "test004545"
    },
    {
        name: "alliswell",
        mesg: "test004545"
    }
]

var result = sample.slice().sort((a,b) => a.name.localeCompare(b.name, undefined, {numeric: true}));
console.log(result);

var chars =_.orderBy(sample, [user => user.name.toLowerCase()], ['asc']);
 
console.log(chars);

According to the lodash docs the API of sortBy is:

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

In your case, the collection is your sample array and your [iteratees=[_.identity]] should be a function or an array which returns the key you want to sort.

So this is probably what you were going for:

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

OR

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