Advanced tools
Package description
The xtend npm package is a utility for shallowly copying all properties from one or more source objects to a new object. It is useful for extending objects without modifying the original object, making it ideal for configurations, options, and default settings manipulation.
Extending an object
This feature allows you to combine properties from one or more source objects into a new object. The properties from the source objects are copied into the new object, with later sources' properties overwriting earlier ones.
var extend = require('xtend');
var object = extend({key1: 'value1'}, {key2: 'value2'});
console.log(object);Similar to xtend, object-assign is used for copying the values of all enumerable own properties from one or more source objects to a target object. It uses Object.assign() method which is built-in in ES6, making it a more modern alternative to xtend.
Lodash's merge function offers deep merging capabilities, in contrast to xtend's shallow copy approach. This makes lodash.merge more suitable for complex object structures where nested properties also need to be merged.
Readme
Extend like a boss
xtend is a basic utility library which allows you to extend an object by appending all of the properties from each object in a list. When there are identical properties, the right-most property takes precedence.
var extend = require("xtend")
// extend returns a new object. Does not mutate arguments
var combination = extend({
a: "a",
b: "c"
}, {
b: "b"
})
// { a: "a", b: "b" }
