Sort array of objects by property

Question

Hello everyone I need a function so that i can sort an array of objects alphabeticaly by a certain property value.

Let say i have this array:

var myObj = [{Name: 'John'},
             {Name: 2.10},
             {Name: 'Andrew'},
             {Name: 10},
             {Name: 2.101}
            ];

The result should be 2.10, 2.101, 10, 'Andrew', 'John'. I need this sorting beacause in my program the Name property can be either a name as 'John' or and IP (like 1.0.0.14) or even a MAC address(97948453855)...

I have managed some sorting but it doesnt seem to work perfectly for both strings and numbers.

Thank you!

You could check for string and use the delta as first result part, or take the nummerical delta or at last the string comparison.

var array = [{ Name: 'John' }, { Name: 2.10 }, { Name: 'Andrew' }, { Name: 10 }, { Name: 2.101 }];
            
array.sort(function (a, b) {
    return (typeof a.Name === 'string') - (typeof b.Name === 'string') || a.Name - b.Name || a.Name.localeCompare(b.Name);
});

console.log(array);
