Fills an existing object with new properties, but only for the keys that already exist.
This also works recursive.
NPM
npm install --save object-fill
Yarn
yarn add object-fill
const newDestination = objectFill(destination, source)destination- the existing objectsource- the data that is inserted into the destination
returns: the new object
const objectFill = require('object-fill');
const destination = {
foo: 'something',
bar: 'another thing',
};
const source = {
bar: 'a new string',
baz: 'an irrelevant string',
}
const newDestination = objectFill(destination, source);
/* newDestination:
* {
* foo: 'something',
* bar: 'a new string'
* }
