How do I console.log every element in an array?

Question

I'm having trouble with this question related to the forEach method. I've tried every way of writing this code out that I could think of but question one is still wrong every time.

function exerciseOne(names){

// Exercise One: In this exercise you will be given and array called names. 

// Using the forEach method and a callback as it's only argument, console log

// each of the names.
}


// MY CODE: 

function logNames(name){

  console.log(name);
}

 names.forEach(logNames);

Answer 1

In your code you are logging the whole array. Use forEach method on array and log the element.

You need to pass a callback to forEach() the first element inside callback will be the element of array thought which its iterating. Just log that.

function exerciseOne(names){
  names.forEach(x => console.log(x));
}
exerciseOne(['John','peter','mart'])

Arrow function may confuse you. With normal function it will be

function exerciseOne(names){
  names.forEach(function(x){
    console.log(x)
  });
}
exerciseOne(['John','peter','mart'])

Answer 2

Just use console.log as the callback, logging the first parameter (the current item) each time:

function exerciseOne(names) {
  names.forEach(name => console.log(name));
}
exerciseOne(["Jack", "Joe", "John", "Bob"]);
