	{
		console.log(person.toString());
	}
	
	public static printPersons(persons : Array<Person>) : void

Main.ts file:

let persons = new Array<Person>();

persons.push(new Person('John', 30));

Note: above source code uses https://requirejs.org/ modules loader.

Compilation and running:

Open console (e.g. Bash)
Go to project directory
Run tsc program to compile all files to one
Open index.htm in web browser

Bash console preview:

$ cd /C/Project
$ tsc

/C/Project directory preview:

Notes:

after tsc command run three new files (out.*) should appear.
out.d.ts contains all declarations (useful for intellisense and intengration out.js file with other typescript projects)
out.js.map contains development mapping for debug process
out.js contains all sourcecode transpiled to single javascript file

Web browser preview:

Download all source code from one place here.
