Removing object properties with Lodash

Question

I have to remove unwanted object properties that do not match my model. How can I achieve it with Lodash?

My model is:

var model = {
   fname: null,
   lna

You can easily do this using _.pick:

var model = {
  fname: null,
  lname: null
};

var credentials = {
  fname: 'abc',
  lname: 'xyz',
  age: 2
};

var result = _.pick(credentials, _.keys(model));


console.log('result =', result);

But you can simply use pure JavaScript (specially if you use ECMAScript 6), like this:

const model = {
  fname: null,
  lname: null
};

const credentials = {
  fname: 'abc',
  lname: 'xyz',
  age: 2
};

const newModel = {};

Object.keys(model).forEach(key => newModel[key] = credentials[key]);

console.log('newModel =', newModel);
