What is the right syntax to cast a string to JSON in Angular2? I tried:
var someString;
someString.toJSON(); //or someString.toJson();
it says: someString.toJSON is not a function
I'm lost because it was working with Angular1.
If I try to add an attribute directly on my string (which is formatted like a true JSON):
var someString;
someString.att = 'test';
it says: TypeError: Cannot create property 'att' on string '...'

Angular2 uses JavaScript functions unlike Angular1.
Angular1 implements its own functions which is a bad thing.
In Angular2 just use pure JavaScript.
var json = JSON.parse(string);
Try using JSON.parse()
var someString: string = "your JSON String here";
var jsonObject : any = JSON.parse(someString)
