Tell us what’s happening:

hi guys who can help me with step 40 of Java script

Your code so far

const character = "#";
const count = 8;
const rows = [];

for (let i = 0; i < count; i = i + 1) {
  rows.push(i);
}

let result = ""


// User Editable Region

for(const value of rows) {};

// User Editable Region


console.log(result);

Hello there!
I hope this syntax will guide you.

  statement

Here is a link as well.

hello sir,
tnx a lot but i need a little bit more clue
i saw this pattern on the link you sent me.
and wrote down some thing like that:
const rows =[‘0’,‘1’,‘2’];
for (const value of rows );{console.log(rows);}
but it was wrong
and the explanation for being wrong is " you should declare a row variable"
is nt this"const rows =[‘0’,‘1’,‘2’];" or this “let rows” declaring rows variable?!
best regard,

In the place where you have the value, you should have the variable provided in the lesson.

you mean the variables that provided in step 40 :thinking:
you mean this variables=( i = 0; i < count; i = i + 1)??
or i should use the row variable that provided in prior lessons like this:
“Naomi”, “Quincy”, “CamperChan” ???

6

The first one is not a variable, those are just statements for the loop. Use the second option.

i go for it and wrotr some thing like this:

for (const “Naomi”,“Quincy”,“CamperChan” for rows;){}
but it is still not the solution!

this is not a valid variable name, you need to use a valid variable name to access the values in rows

if you mean this variable

const rows= “iterator”,“condition”,“iteration”;
for(const values of rows;){console.log(rows);}

still not the answer!!

Hi there, you seem to be quite confused about this step which is quite normal for someone new to programming. So may I suggest that you read the following page which talks about for loops with more examples. This should help you make progress I believe.

Create a for...of loop to iterate through your rows array, assigning each value to a row variable.

You are very close in what you originally wrote. Step 40 at the end sets out everything to include in the for … of code, as per the Example.

What you initially had just needs to update the value variable name.

The variable is automatically assigned the current element in the array on each iteration.

const array = [1, 2, 3];

for (const element of array) {
  console.log(element); // 1, 2, 3
}

Create a for...of loop to iterate through your rows array, assigning each value to a row variable.

So row is the identifier name you should use for that variable.

tnx
but really cant figure the answer when I write : for( const value of rows;){console.log(rows);}
it just tell me " you should declare rows variable"
but when i declare it like this : “const rows = [iterator,condition,iteration];” or this : "const rows = [Naomi,Quincy,Champer Chan]
or this const rows= [0,1,2,3,4,5,6,7],
it just told me you have already declared row variable!!!

17

does it say rows or does it say row? Because you are asked to use a specific name for the variable of the loop, which is not value
