请各位大佬指点！一个对象怎么删除等于0的key值

Question

letarr=[{allotQuantity:0,a:1},{allotQuantity:1,a:2}]如果allotQuantity等于0就删除这条数组对象，该怎么写？

Answer 1

arr.map(i=>{
i.allotQuantity==0?deletei.allotQuantity:null
returni
})
???到底删对象还是对象的key?
                            

Answer 2

letnewArr=arr.filter((item,key)=>{
returnitem.allotQuantity!=0
})
console.log(newArr)
