title: Angular Reactive Forms controls vs Get
body: <p>What is the difference between when i get the values in Reactive forms in below ways:</p>
  
  <pre><code>this.someForm.controls['firstName'].value
  this.someForm.get('firstName').value
  
  public someForm: FormGroup = this.formBuilder.group({
    firstName: ['', Validators.required],
  });
  
  this.someForm.controls['firstName'].value
  this.someForm.get('firstName').value&lt;br&gt;
  </code></pre>
  
  <p>Above is my form and two different ways to get values from the form. But what is the difference b/w both ways if any ?</p>
