I am trying to create a new array of objects without the gender field. Can you identify any mistakes in my code?
let dataSets = [
{ name: "Tim", gender: "male", age: 20 },
{ name: "Sue", gender: "female", age: 25 },
{ name: "Sam", gender: "male", age: 30 }
];
let newArray = dataSets.slice();
let utilities = {
filterFields: function () {
let argumentsArr = [].slice.call(arguments);
for (let i = 0; i < newArray.length; i++) {
for (let key in newArray[i]) {
for (let j = 0; j < argumentsArr.length; j++) {
if (key !== argumentsArr[j]) {
delete key;
return newArray;
}
}
}
}
}
};
const results = utilities.filterFields("name", "age");// specify fields to keep
console.log(results);
