Passo 42 Criando um gerador de pirâmide

Meu código:

for (const row of rows) {
    result = result + "\n" + row;
}

O que está errado?
Qual o código correto?

Can you please link to the challenge step you are doing.

I’ve edited your post to improve the readability of the code. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').
