  <p>I have used the same code in my Visual Studio Code and it is working fine without giving any errors but here in StackBlitz, it is giving errors
  The only difference in both is that in my Visual Studio, Angular Version 8 is installed but here I am using Angular version 9,
  Please can anybody see what is the problem with the code and suggest me some changes,</p>
