Typescript objects serialization?

by

Use Interfaces to get strong types:

// Creating 
var foo:any = {};
foo.x = 3;
foo.y='123';

var jsonString = JSON.stringify(foo);
alert(jsonString);


// Reading
interface Bar{
    x:number;
    y?:string; 
}

var baz:Bar = JSON.parse(jsonString);
alert(baz.y);

And use type assertion “<>” if you need to.
