Frontend Orientation Syntax Error

[wokwen]

• There is an error in the frontend typescript tutorial under "Class and Interface Construction".
  In the Student class, the constructor signature says "constructor(name: string, year: int, adr: string)" instead of
  "constructor(name: string, year: number, adr: string)"

• Also, in higher.order.functions.md, under "Functions as Variables. the first line after the comment in the code snippet says
  "let name: name = value;" instead of "let name: type = value;"
