How does lodash's mergeDeep function work?

Can you explain how lodash's mergeDeep function works?

Sure! The mergeDeep function in lodash is used to deeply merge two or more objects. It combines properties from the source objects into the destination object, recursively merging nested objects.

What happens if there are conflicting properties?

If there are conflicting properties, the values from the source objects will overwrite the values in the destination object. This means the last source object's value will take precedence.

Can you give me an example of using mergeDeep?

Absolutely! Here's a simple example:

const obj1 = { a: 1, b: { c: 2 } };
const obj2 = { b: { d: 3 }, e: 4 };
const result = _.mergeDeep(obj1, obj2);
console.log(result);
// Output: { a: 1, b: { c: 2, d: 3 }, e: 4 }
