Steps to reproduce:

Hi Team,

When I'm searching for a topic "Variable hoisting" in "https://developer.mozilla.org/" I came to know that there is a mistake in the output of a sample code given in the site.


Actual results:

Issue: Please find the below code
var x;
console.log(x === undefined); // logs "true"
x = 3;


Expected results:

The above code should actually logs "false" due to Variable Hoisting is accepted in Javascript.

Provide the URL to the documentation page with the error, please.
Is it https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Grammar_and_types ?

Yes, that is the URL and kindly go to the topic "Variable hoisting" for the issue.

Comment 3

[Eric Shepherd [:sheppy]]

I confirm that the "true" in the comments here should be "false" and have now fixed it.
