I was just start learn angular but I can't understand why we not work settimeout() outside the-CodePudding

export class ServerComponent implements OnInit { 

    show = false;

    setTimeout(() => {
        this.show = true;
    }, 2000);
  
    constructor(){
    }
    
    ngOnInit(){

    }
}

CodePudding user response：

You cannot put setTimeout or anything that isn't a property of method inside a class definition.

Make sure you understand Classes properly!

The right way to do this would be to put the setTimeout inside your constructor function

CodePudding user response：

Set timeout is basically a prebuilt library function (method) with two parameters.

callback function
timeout in milliseconds

so what you trying to do is calling a existing library function outside a method or constructor which is not allowed.
