Lodash is a JavaScript library that provides helpful utility functions for manipulating data. It can be used to find and update an object in a JavaScript array. The .find() and .assign() functions can be used together to accomplish this.
The _.find() function takes a collection (array, object, etc.) and a predicate (function) as arguments. It will iterate through the collection and return the first element that satisfies the predicate.
The _.assign() function is used to copy the values of all enumerable own properties from one or more source objects to a target object.
For example, given the following array of objects:
const array = [
{ id: 1, name: 'Alice' },
{ id: 2, name: 'Bob' }
]
We can use Lodash to find the object with an id of 2 and update its name to 'Charlie':
const updatedObject = _.assign(
_.find(array, {id: 2}),
{name: 'Charlie'}
);
console.log(updatedObject);
// { id: 2, name: 'Charlie' }
The .find() function will return the object with an id of 2, and the .assign() function will copy the new name value to the object, returning the updated object.
