removing a column from an array in javascript-CodePudding

I have a multidimentional array in javascript like this

Arr[i].ProductId
Arr[i].ProductName
Arr[i].ProductCode
Arr[i].ProductDescription
Arr[i].ProductOrigin
Arr[i].ProductInfo

Arr is populated with data when everything is done with Arr,I want to have another array without (ProductCode,ProductOrigin,ProductInfo) columns.

I have done this

var list2 = JSON.parse(JSON.stringify(Arr));
for (i in list2) {
    delete list2[i].ProductCode;
    delete list2[i].ProductOrigin;
    delete list2[i].ProductInfo;
}

this is iterating through the array. is it possible to remove the Columns without iterating? or what is the better solution for that?

CodePudding user response：

You need to iterate over the list to get the new version of every element. Another way to do this is using Array#map:

const list2 = Arr.map(({ ProductCode, ProductOrigin, ProductInfo, ...e }) => e);
