赋值表达式的左侧在Angular2中不能为常量或只读属性

Question

Here's how my code looks like

this.timezones = moment.tz.names();
for(let timezone in this.timezones) {
  this.timezones[timezone] = this.timezones[timezone] +' '+ moment.tz(this.timezones[timezone]).format('Z z');
}

I am getting the above mentioned error in line present inside for loop, I didn't get this error until i upgraded to angular2.1

is there any other way to access the elements of timezones variable to make it writable as well?

Answer 1

as per docs of moment timezone

moment.tz.names(); // String[]

gives string array.

now,

this.timezones[timezone] is undefined.
