meta charset...

I've noticed two ways of writeing "meta charset":

1.<meta charset="utf-8"> 2.<meta name="charset" value="utf-8">

The 1st one is correct. But what about the other one? For example, right now I'm useing PHPStorm as an IDE, and it does not recognize/allow to use attribute "value".

The first example is correct, but the second is not (where did you see that?).

The kind of metadata associated with the tag is based on the other attributes:

  • If name is set, it is document-level metadata, applying to the whole page.
  • If charset is set, it is a charset declaration — the character encoding used by the webpage.

The possible values for the "name" attribute do not include "charset".

For more information see the MDN page on the "meta" tag.

it appears in one of the "Challenge Task" in JavaScript basic lessons.

Read the MDN page for yourself, then you might want to report that task as a bug to Support. Be sure to give them a link to the challenge page.
