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

Using Lodash to merge two JavaScript objects is a simple process. Below is an example of how to do it:

const _ = require('lodash');

const obj1 = {
    a: 'a',
    b: 'b'
};

const obj2 = {
    c: 'c',
    d: 'd'
};

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

console.log(mergedObj);

// Output: { a: 'a', b: 'b', c: 'c', d: 'd' }

The code above uses the require() function to import the Lodash library, then creates two objects obj1 and obj2. The _.merge() function is then used to merge the two objects into a single object mergedObj. The output of the code is { a: 'a', b: 'b', c: 'c', d: 'd' }.

The code can be broken down as follows:

1. const _ = require('lodash'); - This imports the Lodash library.
2. const obj1 = { a: 'a', b: 'b' }; - This creates an object obj1 with two properties a and b.
3. const obj2 = { c: 'c', d: 'd' }; - This creates an object obj2 with two properties c and d.
4. const mergedObj = _.merge(obj1, obj2); - This uses the _.merge() function to merge obj1 and obj2 into a single object mergedObj.
5. console.log(mergedObj); - This logs the merged object mergedObj to the console.
