TypeScript Unexpected token, A constructor, method, accessor or property was expected

Solution 1
You shouldn't use the function
keyword in a Typescript class definition. Try this instead:
class Test {
add(x: number, y: number): number {
return x + y;
}
}
Solution 2
TypeScript does not allow function
declarations as class members; it has a slightly different syntax for that...
class Test
{
// This will bind the add method to Test.prototype
add(x: number, y: number): number
{
return x + y;
}
// This will create a closure based method within the Test class
add2 = (x: number, y: number) => {
return x + y;
}
}

Just trying to write a function within a class using typescript.
class Test { function add(x: number, y: number): number { return x + y; } }
This results in the following error:
TypeScript Unexpected token, A constructor, method, accessor or property was expected.
I copied the example from: https://www.typescriptlang.org/docs/handbook/functions.html
Am I missing something? I'm confused!
