Copy
const today = new Date();
console.log(today.getWeekDay());

What is the return type in the function below?

Copy
function logMessage(message: string) {
  return console.log(message);
}

What are correct type annotations for creating an array of dates?

What will TypeScript infer the type of the people variable to be in the declaration below?

Copy

We have a function below that takes in a varying number of message parameters and outputs them to the console. How can we strongly-type the messages rest parameter so that only string types can be passed?

Copy
function outputMessages(...messages) {
    messages.forEach(message => console.log(message));
}

Consider the function below that calls a function in a 3rd party library that returns the result a calculation. The code isn't strongly-typed because thirdPartyCalculation returns a value of type any. Is it possible to use the unknown type to make the code more strongly-typed?

Copy
function doWork() {
  const result = thirdPartyCalculation();
  return result + 1;
}
