What Is the Equivalent Of Jquery $.Extend() In Ember.js?

2 minutes read

In Ember.js, the equivalent of jQuery's $.extend() function is Ember.assign(). This function combines the properties of two or more objects into a single object, with later properties overwriting earlier ones. Ember.assign() is commonly used in Ember applications for merging default configurations with user-defined options, among other things.


What is the Ember.js function for object merging, akin to using $.extend() in jQuery?

In Ember.js, you can use Ember.assign() to merge objects. This is similar to using $.extend() in jQuery.


For example:

1
2
3
4
5
6

let obj1 = { foo: 'bar' };
let obj2 = { baz: 'qux' };

let mergedObj = Ember.assign({}, obj1, obj2);

console.log(mergedObj); // { foo: 'bar', baz: 'qux' }


Ember.assign() is used to shallow merge the properties of multiple objects into a target object.


What is the Ember.js equivalent function for merging objects, akin to utilizing $.extend() in jQuery?

In Ember.js, you can merge objects using the assign() function. Here is an example of how you can achieve this:

1
2
3
4
5
6

import { assign } from '@ember/polyfills';

let obj1 = { foo: 1, bar: 2 };
let obj2 = { baz: 3 };

let mergedObject = assign({}, obj1, obj2);

console.log(mergedObject);
// Output: { foo: 1, bar: 2, baz: 3 }


In this example, we use the assign() function from the @ember/polyfills package to merge two objects obj1 and obj2. The first argument passed to assign() is an empty object, which serves as the target object for merging.


What is the Ember.js method for extending objects, like jQuery's $.extend()?

In Ember.js, you can extend objects using the Ember.merge() method. This method is similar to jQuery's $.extend() method and allows you to merge the properties of one or more objects into a target object. Here is an example of how you can use Ember.merge():

1

let target = { prop1: 'value1' };
let source = { prop2: 'value2' };

Ember.merge(target, source);

console.log(target); // { prop1: 'value1', prop2: 'value2' }


In this example, the properties of the source object are merged into the target object using Ember.merge(). This allows you to easily extend objects in Ember.js.
