        mesg: "test000"
    },
    {
        name: "Ballside",

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


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

Answer 2

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;}]);
