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

Question

Just trying to write a function within a class using typescript.

class Test 
{
    function add(x: number, y: number): number {
        return x + y;
    }
}         


        

Answer 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;
    }
}
