Get an error when I call object's properties in Array

Question

In typescript code I have an array with objects in it. When I call \"getUsers(users)\" function, it returns the result as I need, but in console I get this error \"Uncaught Type

Answer 1

Your for loop exceeds the available array items. The heighest ID is users.length - 1.

So the easiest way is to remove the equal-sign.

Also think of using the buildt in forEach or map function like this:

function getUsers( users ) {
  users.forEach( u => {
    console.log( `${ u.firstName } is ${ u.age } years old!` );
  } );
}
