Angular 5 - “Cannot read property of undefined”

Question

In Angular 5, for input

Answer 1

I am also getting same issue in my component.html file where I have defined the ngModel property to client.firstName, while you are creating object in component.ts file make sure object should be client. for example client : Client = { firstName:'', lastName:'', email:'', phone:'', balance:0 } Client is interface. small letter client is object which I mentioned in the component.html.
