How do I use lodash's merge function in JavaScript?

The _.merge function in Lodash is used to deeply merge two or more objects. It combines properties of the source objects into the destination object.

Can you show me a simple example of how it works?

Sure! Here's a basic example:

const _ = require('lodash');

const object1 = { a: 1, b: { c: 2 } };
const object2 = { b: { d: 3 }, e: 4 };

const merged = _.merge(object1, object2);
console.log(merged);
// Output: { a: 1, b: { c: 2, d: 3 }, e: 4 }

What happens if there are conflicting properties?

In case of conflicting properties, _.merge will recursively merge the properties. If the properties are objects, it will merge them; if they are not, the value from the last object will overwrite the previous one.
