Angular 6 Basics 9 - Data binding and async

So angular is javaScript but without people debating weather or not it is a "TRUE" object-oriented language?

property needs to be set: dateMessage: string | undefined; to avoid this error: ' Property 'dateMessage' has no initializer and is not definitely assigned in the constructor'

I did the same thing as you, but got this error

Property 'dateMessage' has no initializer and is not definitely assigned in the constructor

Thank you very much! Appreciated

will this code instantiate constructor again and again?

How can i get some DOM information, if async comes undefined?

شكرا

.toLocaleTimeString() is not giving time in AM /PM so please help

like always, thx for your tutorials

Async???

When I tried to create a new method inside the component class and put the same functionality as mentioned in the fat arrow function, it is not recognizing this keyword. Why is it so?

constructor() {
setInterval(updateTime(),1000)

}

updateTime(){
let currentDate = new Date();
this.dateMessage = currentDate.toDateString()+ ' '+ currentDate.toLocaleTimeString();
}


Can someone please answer this?

Hello professor.
Could you explain to me what 'this.' mean in this context? Thank you!
