Lodash，以滿足對象的要求

Question

例子：

Animals = [{Name: 'Dog', Id: 0}, 
      {Name: 'Cat', Id: 1}, 
      {Name: 'Mouse', Id: null}] 

如何採取一切物體其中id是不是空到新的陣列？

預期輸出：

NewArray = [{Name: 'Dog', Id: 0}, 
      {Name: 'Cat', Id: 1}] 

Answer 1

與_.filter

var Animals = [{Name: 'Dog', Id: 0},{Name: 'Cat', Id: 1},{Name: 'Mouse', Id:null}] 
 
var newArray =_.filter(Animals ,a=> a.Id != null) 
 
console.log(newArray)
