What is merge?

The merge npm package is a utility that allows you to merge multiple objects into one. It is useful when you want to combine configurations, settings, or other data structures in JavaScript. It performs a deep merge by default, meaning that it recursively merges properties of objects, but it can also be configured to perform a shallow merge.

What are merge's main functionalities?

Deep Merge

This feature allows for the deep merging of objects, meaning that nested objects will also be merged together. The code sample demonstrates merging two objects with nested properties.

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

Shallow Merge

This feature allows for the shallow merging of objects, which means that it will not recursively merge nested objects. The code sample demonstrates merging two objects without combining the nested properties.

{"const merge = require('merge');
const object1 = { a: 1, b: { c: 2 } };
const object2 = { b: { d: 3 }, e: 4 };
const mergedObject = merge.recursive(false, object1, object2);
console.log(mergedObject); // Output: { a: 1, b: { d: 3 }, e: 4 }"}
