根据数组中的对象的某个属性值排序

var arr = [
    {name:'zopp',age:0,priority:'a'},
    {name:'gpp',age:18,priority:'f'},
    {name:'yjj',age:8,priority:'d'}
];

function compare(property){
    return function(a,b){
        var value1 = a[property];
        var value2 = b[property];
        return value2 - value1;
    }   
}
console.log(arr.sort(compare('age')))
