javascript-lodashHow do I use Lodash to merge two JavaScript objects?

Lodash is a JavaScript library that provides utility functions for common programming tasks. One of these tasks is merging two JavaScript objects. To do this, you can use the _.merge() function. This function takes two objects as arguments and returns a new object that contains the combined properties of both.

For example:

const obj1 = {
  a: 1,
  b: 2
};

const obj2 = {
  c: 3,
  d: 4
};

const mergedObj = _.merge(obj1, obj2);

console.log(mergedObj);

Output example

{
  a: 1,
  b: 2,
  c: 3,
  d: 4
}

The _.merge() function can also take a third argument, which is an object containing options for customizing the merging process. This argument is optional.

Code explanation

1. const obj1 = { a: 1, b: 2 }; - This is the first object to be merged.
2. const obj2 = { c: 3, d: 4 }; - This is the second object to be merged.
3. const mergedObj = _.merge(obj1, obj2); - This uses the _.merge() function to combine the two objects.
4. console.log(mergedObj); - This logs the result of the merging process.
