Template Logic Avoid Example

components.my-component\.js

import Component from '@glimmer/component';

export default class extends Component {
}

controllers.application\.js

import Controller from '@ember/controller';

class Person {
	constructor(first, last) {
  	this.firstName = first;
    this.lastName = last;
  }
  
  firstName;
  lastName;
  
  get name() {
  	return `${this.firstName} ${this.lastName}`;
  }
}

export default class extends Controller {
  person = new Person('Jackie', 'Chiles');
};

templates.application\.hbs

<MyComponent @person={{this.person}} />

templates.components.my-component\.hbs

<div>{{@person.name}}</div>
<input disabled={{not (and this.isFeatureToggleOn this.enableInput )}} />
