Suppose, you have a variable defined like this:

let helloWorld = "Hello World";

What statement is correct?

Please, choose how the TypeScript works with the code like this:

interface Course {
  name: string;
  totalHours: number;
  id: number;
}

const course: Course = {
  name: "Math",
  totalHours: 50
};

interface Person {
  name: string;
  surname: string;
}
 
function logPerson(p: Person) {
  console.log(`${p.name}, ${p.surname}`);
}
 
const person = { name: "Paul", surname: "Mass" };
logPerson(person);

Please, select the type representing any possible type of React node (ReactElement + primitive JS types)

Please, select the type the following statement is about:

A type representing a concept of React Element - representation of a native DOM component (e.g. <div />), or a user-defined composite component (e.g. <MyComponent />)

Please, create a type definition for an array where each value is an object with name property of string type

Please, select how we can annotate a function that takes no arguments and returns a value of type Course

Is the code below correct? What is the result of compilation of this code?

function loggingIdentity<Type>(arg: Type): Type {
  console.log(arg.length);
  return arg;
}
