Sort array of objects by string property value

Question

I have an array of JavaScript objects:

var objs = [ 

{ first_nom: 'Lazslo', last_nom: 'Jamf' }, 

{ first_nom: 'Pig', last_nom: 'Bodine' }, 

{ first_nom: 'Pirate', last_nom: 'Prentice' } 

];

How can I sort them by the value of last_nom in JavaScript?

I know about sort(a,b), but that only seems to work on strings and numbers. Do I need to add a toString() method to my objects?

Answer 1

You can sort an array of objects by string property value by using the below-mentioned code:-

function compare( a,     b ) {

if ( a.last_nom < b.last_nom ){ 

return -1; 

} 

if ( a.last_nom > b.last_nom ){ 

return 1; 

} 

return 0; 

} 

objs.sort( compare );
