Learn Introductory JavaScript by Building a Pyramid Generator - Step 42

Tell us what’s happening:

I need help with concatenation. It’s a lot harder than I thought.

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 row of rows) {

}

// User Editable Region


console.log(result);

Hi @coding_kid13 ,

Concatenation means appending a new string to an existing string.

For example:

We start with result as an empty string:

let result = "";

We concatenate letter "A" to result:

result = result + "A";

Now, result is "A".

We continue to concatenate letter "B" to result:

result = result + "B";

Now, result is "AB".

That’s called concatenation.

Now, the instruction asked us to:

concatenate row to result inside the for loop

What should we do?
