Angular 2 typescript 1.8 compliation error for loop statement

Question

I want to loop on an array .

There is my code:

@Input()
applicationLinks: ApplicationLink[];


applicationRows: ApplicationLinkRow[];
for(applicationLink in applicationLinks) {
    applicationRows.push(applicationLink);
}

in gives a compilation error

(= expected).

i had try also

for(applicationLink of applicationLinks)
for(var applicationLink in applicationLinks)
for(var applicationLink of applicationLinks)

Each time gives a compilation error !

You need to move this code into a method or the constructor

for(applicationLink in applicationLinks) {
    applicationRows.push(applicationLink);
}

should be something like:

class SomeClass {
  @Input()
  applicationLinks: ApplicationLink[];


  applicationRows: ApplicationLinkRow[];

  someMethod() {
    for(applicationLink in applicationLinks) {
        applicationRows.push(applicationLink);
    }
  }
}
