Hello! I'm stuck on this task. Please guide me.

Task: Implement a function printArray that should take the array and print it to the screen using console.log Each element should be printed on the separate line

What I'm doing is the same as the following:

const printArray = (arr) => {
console.log( arr.join( " " ) );
};
const months = [ 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec' ];
printArray( months );

Noe, this should come up with printing each element of the array in a separate line but its printing the given below result to the console.

Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec

instead of,

Jan
Feb
Mar
Apr
May
Jun
Jul
Aug
Sep
Oct
Nov
Dec

Why is that so?

I've tried to solve the issue by changing arr.join(" ") to arr.join("/n") in the following code but that still doesn't work for me to get this task completed, even though it's giving me the expected answer. Why?

PREVIOUS CODE
const printArray = (arr) => {
console.log( arr.join( " " ) );
};
const months = [ 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec' ];
printArray( months );

LATEST CODE
const printArray = (arr) => {
console.log( arr.join( "/n" ) );
};
const months = [ 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec' ];
printArray( months );

The task states the following errors:

printArray should print as many strings as there are elements in the array
printArray should print all the elements of the array

mrmalik610 your code prints a single string.

Instead of using join, use the for loop and print each array element to the console separately.

Coderslang_Master Thanks! This works.

ihave done the task
const months = [ 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec' ];

for(var i = 0; i < months.length ; i++){
printArray( months[i] );
    }

the output is:
Jan
Feb
Mar
Apr
May
Jun
Jul
Aug
Sep
Oct
Nov
Dec
but i receive errors

Coderslang_Master

edith the loop should be inside of the printArray

i tried every combination that came to my mind and i also watched other tutorials but to my disappointment, i could't solve it. please give me some pretty clear hints. here's my code:

export const printArray = (months) => {
for (i=0; i<months.length; i++) {
console.log(months);
}
}

import { printArray } from './helper.js';

const months = [ 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec' ];

printArray(months);

hi, try again to read the lecture on cycles. pay special attention to this:

we show on the screen not the entire array, but in turn each of its elements

salton thanks
