Angular Convert Array into string

Question

I have the following array (testArray) and i wish to extract all the states to string ('Arizona','Alaska','Florida','Hawaii','Gujarat','Goa','Punjab'...). Are there any simpler ways to do that?

let testArray: State[];
testArray = this.getStates();

getStates() {
 return [
  new State(1, 1, 'Arizona'),
  new State(2, 1, 'Alaska'),
  new State(3, 1, 'Florida'),
  new State(4, 1, 'Hawaii'),
  new State(5, 2, 'Gujarat'),
  new State(6, 2, 'Goa'),
  new State(7, 2, 'Punjab'),
  new State(8, 3, 'Queensland'),
  new State(9, 3, 'South Australia'),
  new State(10, 3, 'Tasmania'),
  new State(11, 4, 'Penang')
 ];
}

Answer 1

The simplest way is as follows

getStates().map(x=>x.StateName).join(",")

Example is given below

function State(id,val,StateName) {
  this.id = id;
  this.val = val;
  this.StateName = StateName;
}

function getStates() {
 return [
  new State(1, 1, 'Arizona'),
  new State(2, 1, 'Alaska'),
  new State(3, 1, 'Florida'),
  new State(4, 1, 'Hawaii'),
  new State(5, 2, 'Gujarat'),
  new State(6, 2, 'Goa'),
  new State(7, 2, 'Punjab'),
  new State(8, 3, 'Queensland'),
  new State(9, 3, 'South Australia'),
  new State(10, 3, 'Tasmania'),
  new State(11, 4, 'Penang')
 ];
}

//Simplest Way is as follows
console.log(getStates().map(x=>x.StateName).join(","))
