JavaScript array sort on 2 properties

Question

I have a JSON array of objects that looks something like this:

var garments [{
    name: \'Garment 1\',
    isDesignable: false,
    priority: 3
},{
    name: \'         


        

Answer 1

garments.sort(function (a, b) {
    if (a.isDesignable == b.isDesignable) {
        return a.priority - b.priority;
    } else if (a.isDesignable) {
        return -1;
    } else {
        return 1;
    }
});
