We will learn about how set the model values in Reactive Forms. It is done using SetValue and PatchValue provided by AngularFormsValue module.
SetValue
We use the setValue to update FormGroup, FormControl or FormArray. SetValue requireds that structure of the Formgroup/FormArray should match. Otherwise it will throw an error. SetValue must include all the controls.
PatchValue
PatchValue is used to only update the selected or required values . It will update only matching values in FormArray/FormControl and ignores the rest.
PatchValue can exclude some controls.
