Is that always compulsory for passing it to the console?

array1.forEach(function(element) { console.log(element); });

If you want to log every item to the console separately, you can either use the forEach() method or a for loop.

The forEach() method runs the function once for each array element, by passing it the respective array[i].

Hence, the argument “element” refers to the current element being processed in the array.

Let’s say:

let array1 = [1, 2, 3];

array1.forEach(function(element) {       

When you run your code, it will take each element once and run the provided function, logging it to the console.

Your expected output would be:

// expected output: “1”
// expected output: “2”
// expected output: “3”

Alternatively, you could use a for loop to iterate through the array:

let array1 = [1, 2, 3];

for ( let i = 0; i < array1.length; i++ ) {

I hope this helps!

Thank you so much! although it's not really the information that i was seeking but this definitely helps me in the future! :D

Jenny Le, sorry, I guess I didn't catch what you were aiming at with the question. :) What exactly did you mean?

Oh, actually i have to say sorry cause my question was not clear. I meant i was solving the ForEach loop challenge and i was not sure if i also had to log items to the console or not! But your information was definitely useful! Thank you so much!
