Tell us what’s happening:
I have 2 error that can’t solve
- I’m keep getting this error about " Failed:None of your
header
elements should be empty." but I checked all and I don’t see any that is empty, Chat GPT couldn’t even find so I have no clue how to solve this. - Another error is " Each
.nav-link
should have text that corresponds to theheader
text of its relatedsection
(e.g. if you have a “Hello world” section/header, your#navbar
should have a.nav-link
which has the text “Hello world”)." I also can’t find the problem.
I will really appriciate if you could tell me what should I do.

<h2>Python Overview</h2>
<p>Python, with its clear and concise syntax, provides a range of fundamental data types.</p>
<h3>Python Examples</h3>
<ul>
<li>Boolean: Python uses True and False for boolean values.
<code># Boolean: Python uses True and False for boolean values.<br>
is_python_fun = True<br>
is_learning = False</code>
</li>
<li>None: Equivalent to null in other languages, denoting the absence of a value.
<code>
# None: Equivalent to null in other languages, denoting the absence of a value.<br>
my_variable = None
</code>
</li>
<li>Integer: Represented by numbers like 42 or 0.
<code>
# Integer: Represented by numbers like 42 or 0.<br>
answer_to_everything = 42<br>
zero_value = 0
</code>
</li>
</ul>
<h2>JavaScript Overview</h2>
<p>JavaScript's flexible syntax accommodates various data types essential for web development.</p>
<h3>JavaScript Examples</h3>
<ul>
<li>Boolean: JavaScript uses true and false for boolean values.
<code>
// Boolean: JavaScript uses true and false for boolean values.<br>
let isJavaScriptFun = true;<br>
let isLearning = false;
</code>
</li>
<li>null: A special keyword denoting a null value.
<code>
// null: A special keyword denoting a null value.<br>
let myVariable = null;
</code>
</li>
<li>undefined: A top-level property whose value is undefined.
<code>
// Number: Represented by numbers like 42 or 0.<br>
let answerToEverything = 42;<br>
let zeroValue = 0;<br>
</code>
</li>
</ul>
<p>In summary, both languages share fundamental data types like boolean, but Python uses None for null, while JavaScript uses null.</p>
