It looks like Task 1 is no longer passing

Hello, i'm trying to pass the challenge ( /library/javascript-and-the-dom-2/traversing-the-dom/child-traversal ). The Task 1 passed but when I try to submit the Task 2, I get the error into the subject. Should You help me to find the error? Regards Mattia

app.js 
const section = document.querySelector('section');
let paragraphs = section.children;
for (i=0; i<paragraphs.lenght; i++){
  if (paragraphs[i].tagName = "P"){
    paragraphs[i].style.color = "blue";
  }
}

    <head>
        <title>Child Traversal</title>
    </head>
    <body>

            <p>This is the first paragraph</p>
            <p>This is a slightly longer, second paragraph</p>

I see two issues:

  • you didn't declare the index variable in the for loop (use "let i=0" instead of just "i=0")
  • you wrote "lenght" instead of "length"
