//Here we will provide simple use of FormControl.setValue() method. In our code we have initialized a FormControl and we have a setter method to set value as 'India'.
countryName = new FormControl();

setCountryName() {
    this.countryName.setValue('India');
} 

//Find the HTML template code.

<input [formControl]="countryName">
<button type="button" (click)="setCountryName()">Set Country Name</button>
{{countryName.value}} 
//On click of button, text box and countryName.value will display value as 'India'.
//3. Using setValue() with Options
//We can use FormControl.setValue() with configuration options as following.

this.cityName.setValue('Varanasi', {
  onlySelf: false,
  emitEvent: true, 
  emitModelToViewChange: true,
  emitViewToModelChange: true
}); 

//Find the example where we are setting the emitModelToViewChange value as false.
cityName = new FormControl();
setCityName() {
    this.cityName.setValue('Varanasi', {
      emitModelToViewChange: false
    });
} 

//Find the HTML template code.
<input [formControl]="cityName">
<button type="button" (click)="setCityName()">Set City Name</button>
{{cityName.value}} 

//When we call setValue() by clicking the button, this value in text box will not change but cityName.value will change.
