What is the difference between let todos = this.args; and let { todos } = this.args; in JavaScript? [duplicate]

I am learning Ember.js. I was working on a component class

Here my code:

import Component from '@glimmer/component';
import { action } from '@ember/object';
import { inject as service } from '@ember/service';
import { tracked } from '@glimmer/tracking'

export default class TodoListComponent extends Component {
  @service todoData;

  @tracked canToggle = true;

  get areAllComplete() {
    let  **{todos}**  = this.args;
    
    return todos.every(todo => {
      return todo.isCompleted;
    });
  }
} 

Can anyone tell me What is the difference between let todos = this.args; and let { todos } = this.args; in JavaScript ?
