var details = [
            {
                reference: 'ref-1',
                description: 'desc-1',
                price: 1
            }, {
                reference: '',
                description: '',
                price: ''
            }, {
                reference: 'ref-2',
                description: 'desc-2',
                price: 200
            }, {
                reference: 'ref-3',
                description: 'desc-3',
                price: 3
            }, {
                reference: '',
                description: '',
                price: ''
            }
        ];

        scope.removeEmptyDetails(details);
        expect(details.length).toEqual(3);

scope.removeEmptyDetails = function(details){
            _.remove(details, function(detail){
                return (_.isEmpty(detail.reference) && _.isEmpty(detail.description) && _.isEmpty(detail.price));
            });
        };

简单ES6

['a','b','',,,'w','b'].filter(v => v);

带下划线/Loddash：

一般使用情况：

_.without(array, emptyVal, otherEmptyVal);
_.without([1, 2, 1, 0, 3, 1, 4], 0, 1);

有空：

_.without(['foo', 'bar', '', 'baz', '', '', 'foobar'], '');
--> ["foo", "bar", "baz", "foobar"]

无需参阅lodash文档。

// recursive implementation
function compact(arr) {
        const compactArray = [];
        //base case 
        if(!arr.length) return []
        if(typeof arr[0] !== "undefined" 
          && arr[0]!==null && arr[0] !== " " && 
          arr[0]!== false &&
          arr[0]!== 0){
          compactArray.push(arr[0]);
        }
        return compactArray.concat(compact(arr.slice(1)))
    }
    
    compact([1,0,false,null,undefined,"banana"])`

var a = [{a1: 1, children: [{a1: 2}, undefined, {a1: 3}]}, undefined, {a1: 5}, undefined, {a1: 6}]
function removeNilItemInArray(arr) {
    if (!arr || !arr.length) return;
    for (let i = 0; i < arr.length; i++) {
        if (!arr[i]) {
            arr.splice(i , 1);
            continue;
        }
        removeNilItemInArray(arr[i].children);
    }
}
var b = a;
removeNilItemInArray(a);
// Always keep this memory zone
console.log(b);

这是可行的，我在AppJet中测试了它（你可以复制粘贴代码到它的IDE上，然后按“reload”查看它的工作情况，不需要创建帐户）

/* appjet:version 0.1 */
function Joes_remove(someArray) {
    var newArray = [];
    var element;
    for( element in someArray){
        if(someArray[element]!=undefined ) {
            newArray.push(someArray[element]);
        }
    }
    return newArray;
}

var myArray2 = [1,2,,3,,3,,,0,,,4,,4,,5,,6,,,,];

print("Original array:", myArray2);
print("Clenased array:", Joes_remove(myArray2) );
/*
Returns: [1,2,3,3,0,4,4,5,6]
*/
