[typescript] console.log not working in Angular2 Component (Typescript)

I am relatively new to both Angular2 and typescript. Since typescript is a superset of javascript, I'd expect functions like console.log to work. console.log works perfectly in .ts files when outside a component class but does not work as I'd expect from inside the component class.

// main.ts

import { Component } from '@angular/core';
console.log("Hello1"); //1. This works perfectly

@Component({..)
export class App {
 s: string = "Hello2";
 // console.log(s); //2. This gives compilation error (when uncommented)
 // Error: Function implementation is missing or not immediately following the declaration.
}

Is there anything that I am missing?

The console.log should be wrapped in a function , the "default" function for every class is its constructor so it should be declared there.

import { Component } from '@angular/core';
console.log("Hello1");

 @Component({
  selector: 'hello-console',
})
    export class App {
     s: string = "Hello2";
    constructor(){
     console.log(s); 
    }

}

Also try to update your browser because Angular need latest browser. check: https://angular.io/guide/browser-support

I fixed console.log issue after updating latest browser.
