Advanced tools
Package description
The extend-shallow npm package is used to copy the properties of one or more source objects to a target object. It is a utility for shallowly extending the properties of objects without deeply cloning them.
Shallow extend one object with another
This feature allows you to extend an object by adding properties from another object. The properties are copied over shallowly, meaning that if the property values are objects, they are not deeply cloned.
{"const extend = require('extend-shallow');
const obj1 = { a: 'a' };
const obj2 = { b: 'b' };
const result = extend(obj1, obj2);
// result is { a: 'a', b: 'b' }"}Shallow extend with multiple source objects
This feature allows you to extend an object with properties from multiple source objects. The last source's properties will overwrite the properties of the same name in previous sources if they exist.
{"const extend = require('extend-shallow');
const obj1 = { a: 'a' };
const obj2 = { b: 'b' };
const obj3 = { c: 'c' };
const result = extend(obj1, obj2, obj3);
// result is { a: 'a', b: 'b', c: 'c' }"}The object-assign package is a polyfill for the Object.assign() method, which copies enumerable and own properties from source objects to a target object. It is similar to extend-shallow but is designed to mimic the behavior of the native JavaScript method.
lodash.assign is a method from the Lodash library that assigns own enumerable properties of source objects to the destination object. It is similar to extend-shallow but comes with the additional utility functions provided by Lodash.
deep-extend is similar to extend-shallow but, as the name suggests, performs a deep extend, meaning that it recursively copies property values that are objects, resulting in a deep clone of the source objects' properties.
Readme
Extend an object with the properties of additional objects. node.js/javascript util.
Please consider following this project's author, Jon Schlinkert, and consider starring the project to show your :heart: and support.
Install with npm:
$ npm install --save extend-shallow
var extend = require('extend-shallow');
extend({a: 'b'}, {c: 'd'})
//=> {a: 'b', c: 'd'}
Pass an empty object to shallow clone:
var obj = {};
extend(obj, {a: 'b'}, {c: 'd'})
//=> {a: 'b', c: 'd'}
