Ember.js .setProperties

This is a simple example of when you should use the .setProperties on an Ember object such as the controller.

// search.js
export default Ember.Route.extend({
  setupController(controller, model) {
    this._super(controller, model)
    
    let foods = ["burger", "sandwiches", "pasta"]
    let searchTerm = ""
    let searchResults = []
controller.setProperties({
      foods,
      searchTerm,
      searchResults
    })
  }
})

You would want to do all your logic for the properties that you will be setting to the controller, then using .setProperties , you can set them all at once. I know that when I started using Ember, I set the properties one by one using controller.set(‘propertyName’, propertyValue) which can have a weird flow where as setting all your properties in one place makes more sense.
