utils-merge

What is utils-merge?

The utils-merge package is a simple utility to merge objects in JavaScript. It is often used to combine configurations or settings objects where a base object is extended with properties from another object.

What are utils-merge's main functionalities?

Merging objects

This feature allows you to merge the properties of one object into another. The properties from the second object will overwrite those in the first if they have the same key.

{"const merge = require('utils-merge');
const a = { foo: 'bar' };
const b = { baz: 'qux' };
const c = merge(a, b);
console.log(c); // Output: { foo: 'bar', baz: 'qux' }"}

Other packages similar to utils-merge

extend

The 'extend' package is similar to utils-merge but offers deep or recursive merging of objects. It can also handle arrays and other types, providing more flexibility than utils-merge.

object-assign

The 'object-assign' package is a polyfill for the Object.assign() method which is built into modern JavaScript engines. It is similar to utils-merge but is part of the standard library in ES6 and above.

lodash.merge

The 'lodash.merge' function from the lodash library is a powerful utility that performs a deep merge of own and inherited enumerable string keyed properties of source objects into the destination object. It is more feature-rich compared to utils-merge, handling complex scenarios like deep merging, customizing merge behavior, and merging arrays.
