Convert JSON array of objects to string array using Typescript

Question

I am using Angular 2 (latest version). I am trying to convert a JSON array i.e.

  jsonObject = [
    {"name": "Bill Gates"},
    {"name": "Max Payne"},
    {"name": "Trump"},
    {"name": "Obama"}
  ];

to a string array and store just the value in i.e

arrayList: [string] = [''];

array. I tried to use Stringify method but no luck.

@GlenPierce No unfortunately it didnt work. I tried that before. — Software Ninja

Please print the result of JSON.stringify(jsonObject) and take a screen shot — parik

There is no such thing as a "JSON array". There are just "JavaScript" arrays. There is nothing special here having to do with TypeScript or Angular. TypeScript is just a layer on top of JavaScript with type annotations and inference and checking. — user663031

This should do the job:

names: string[] = jsonObject.map(person => person.name); 

// => ["Bill Gates", "Max Payne", "Trump", "Obama"]
