When there are identical properties, the right-most property takes precedence. ## Examples ```js 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" } ``` ## Stability status: Locked ## MIT Licensed [3]: http://ci.testling.com/Raynos/xtend.png [4]: http://ci.testling.com/Raynos/xtend .jshintrc000066600000001041150435262770006404 0ustar00{ "maxdepth": 4, "maxstatements": 200, "maxcomplexity": 12, "maxlen": 80, "maxparams": 5, "curly": true, "eqeqeq": true, "immed": true, "latedef": false, "noarg": true, "noempty": true, "nonew": true, "undef": true, "unused": "vars", "trailing": true, "quotmark": true, "expr": true, "asi": true, "browser": false, "esnext": true, "devel": false, "node": false, "nonstandard": false, "predef": ["require", "module", "__dirname", "__filename"] } mutable.js000066600000000561150435262770006554 0ustar00module.exports = extend var hasOwnProperty = Object.prototype.hasOwnProperty; function extend(target) { for (var i = 1; i < arguments.length; i++) { var source = arguments[i] for (var key in source) { if (hasOwnProperty.call(source, key)) { target[key] = source[key] } } } return target } test.js000066600000004403150435262770006101 0ustar00var test = require("tape") var extend = require("./") var mutableExtend = require("./mutable") test("merge", function(assert) { var a = { a: "foo" } var b = { b: "bar" } assert.deepEqual(extend(a, b), { a: "foo", b: "bar" }) assert.end() }) test("replace", function(assert) { var a = { a: "foo" } var b = { a: "bar" } assert.deepEqual(extend(a, b), { a: "bar" }) assert.end() }) test("undefined", function(assert) { var a = { a: undefined } var b = { b: "foo" } assert.deepEqual(extend(a, b), { a: undefined, b: "foo" }) assert.deepEqual(extend(b, a), { a: undefined, b: "foo" }) assert.end() }) test("handle 0", function(assert) { var a = { a: "default" } var b = { a: 0 } assert.deepEqual(extend(a, b), { a: 0 }) assert.deepEqual(extend(b, a), { a: "default" }) assert.end() }) test("is immutable", function (assert) { var record = {} extend(record, { foo: "bar" }) assert.equal(record.foo, undefined) assert.end() }) test("null as argument", function (assert) { var a = { foo: "bar" } var b = null var c = void 0 assert.deepEqual(extend(b, a, c), { foo: "bar" }) assert.end() }) test("mutable", function (assert) { var a = { foo: "bar" } mutableExtend(a, { bar: "baz" }) assert.equal(a.bar, "baz") assert.end() }) test("null prototype", function(assert) { var a = { a: "foo" } var b = Object.create(null) b.b = "bar"; assert.deepEqual(extend(a, b), { a: "foo", b: "bar" }) assert.end() }) test("null prototype mutable", function (assert) { var a = { foo: "bar" } var b = Object.create(null) b.bar = "baz"; mutableExtend(a, b) assert.equal(a.bar, "baz") assert.end() }) test("prototype pollution", function (assert) { var a = {} var maliciousPayload = '{"__proto__":{"oops":"It works!"}}' assert.strictEqual(a.oops, undefined) extend({}, maliciousPayload) assert.strictEqual(a.oops, undefined) assert.end() }) test("prototype pollution mutable", function (assert) { var a = {} var maliciousPayload = '{"__proto__":{"oops":"It works!"}}' assert.strictEqual(a.oops, undefined) mutableExtend({}, maliciousPayload) assert.strictEqual(a.oops, undefined) assert.end() }) LICENSE000066600000002066150435262770005574 0ustar00The MIT License (MIT) Copyright (c) 2012-2014 Raynos.
