Why Does This Typescript Output “[Class] is not a constructor.”?

Question

I\'m working in typescript 1.5 in visual studio. I have a main class called app.ts, and another called FizzBuzzManager.ts. I can\'t figure out what is wrong with this code,

Answer 1

at first, make sure that use

///    

to refrence code to another .ts file at typescript root file

to compile typescript files that exist in different file.ts use this command

tsc --out app.js app.ts

because this command converts all typescript files into app.js
