Ember.js Route setProperties() Method

Ember.js is an open-source JavaScript framework used for developing large client-side web applications based on Model-View-Controller (MVC) architecture. Ember.js is one of the most widely used front-end application frameworks. It is made to speed up development and increase productivity. Currently, it is utilized by a large number of websites, including Square, Discourse, Groupon, Linked In, Live Nation, Twitch, and Chipotle.

The setProperties() method is used to get the value of multiple properties at once. We use the getProperties() method with a list of strings or arrays.

Syntax:

setProperties( list );

Parameters:

• list: It is an array of keys to get.

Return Value: Object.

    model() {
        this.set('[]', this.fruits);
        return this;
    }
    setupController(controller, model) {
