javascript-lodashHow can I use Lodash's extend() function in JavaScript?

The Lodash extend() function is a utility method that allows you to merge two or more objects together. It takes in any number of objects as arguments and returns a new object containing all the properties of the objects passed in.

For example, the following code creates two objects and then merges them together using extend():

var object1 = {
  name: 'John',
  age: 30
};

var object2 = {
  job: 'Software Engineer',
  city: 'New York'
};

var mergedObject = _.extend(object1, object2);

The output of this code is:

{
  name: 'John',
  age: 30,
  job: 'Software Engineer',
  city: 'New York'
}

The extend() function works by iterating over each of the objects passed in and copying all of their properties into the new object. If two objects have the same property name, the property from the last object passed in will take precedence.

Here is a breakdown of the code above:

• var object1 = { name: 'John', age: 30 };: This creates an object with two properties, name and age.
• var object2 = { job: 'Software Engineer', city: 'New York' };: This creates an object with two properties, job and city.
• var mergedObject = _.extend(object1, object2);: This uses the extend() function to merge the two objects together.
