Using lodash, how do I set multiple properties on an object?

Question

I have a list of properties, like so:

const list = [
  'creditCardNumber',
  'orderDetails.amount',
  'customerInformation.details.email',
]

Given an object like this:

const someObj = {
  creditCardNumber: '000 0000 0000 0000',
  orderNumber: '1234',
  orderDetails: { amount: 20, date: 'some date' },
  customerInformation: { details: { email: 'some@email.com', joinedOn: 'someDate' } },
  someOtherProp: 'some value',
}

Using lodash , or vanilla JS, is there an easy way to make a copy of the obj, while re-writing the values of locations on the list array (to the same value for eg: [HIDDEN] ) so we get something like this?

{  
  const someObj = {
  creditCardNumber: '[HIDDEN]',
  orderNumber: '1234',
  orderDetails: { amount:'[HIDDEN]', date: 'some date' },
  customerInformation: { details: { email: '[HIDDEN]', joinedOn: 'someDate' } },
  someOtherProp: 'some value',
}

Answer 1

Lodash _.set() accepts dot seperated object paths, so

_.set(obj, 'orderDetails.amount', 'TEST');

Will resolve to:

obj.orderDetails.amount = 'TEST'

Combine that with a loop for each list item to get the desired result:

 const list = [ 'creditCardNumber', 'orderDetails.amount', 'customerInformation.details.email' ]; const someObj = {creditCardNumber: '000 0000 0000 0000', orderNumber: '1234', orderDetails: { amount: 20, date: 'some date' }, customerInformation: { details: { email: 'some@email.com', joinedOn: 'someDate' } }, someOtherProp: 'some value', } const newObj = _.clone(someObj); list.forEach(key => _.set(newObj, key, '[HIDDEN]')); console.log(newObj);

 <script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.21/lodash.min.js"></script>

{
    "creditCardNumber": "[HIDDEN]",
    "orderNumber": "1234",
    "orderDetails":
    {
        "amount": "[HIDDEN]",
        "date": "some date"
    },
    "customerInformation":
    {
        "details":
        {
            "email": "[HIDDEN]",
            "joinedOn": "someDate"
        }
    },
    "someOtherProp": "some value"
}

Note: Using _.clone() to 'clone' the object;)

USING VANILLA JS

Clone object using Object Destructuring and then using forEach add the [HIDDEN] value

 const list = [ "creditCardNumber", "orderDetails.amount", "customerInformation.details.email", ]; const someObj = { creditCardNumber: "000 0000 0000 0000", orderNumber: "1234", orderDetails: { amount: 20, date: "some date" }, customerInformation: { details: { email: "some@email.com", joinedOn: "someDate" }, }, someOtherProp: "some value", }; let clone = {...someObj }; list.forEach((prop) => { const splitProp = prop.split("."); let obj = clone; splitProp.forEach((p, i, arr) => { if (i === arr.length - 1) { obj[p] = `[HIDDEN]`; } else { obj = obj[p]; } }); }); console.log(clone);
