2nd opening move h4?

In a recent game,my opponent (white) opened with e4. 

I (black) responded with e5.

White then with h4. I don't  understand the purpose of that move.   In the Opening Principles / Fundamentals lesson,  the narrator disparages a similar move and stresses the advantages of controlling the center. Yet, on review, the engine stated "h4 is good.  It is a fair move"  What would be the reason for such a  move?  Thanks!

The engine has a tendency to evaluate almost all moves as acceptable during the first 5-10moves of a game if they don’t lose any material because it’s capable of defending even if it’s a few moves behind in development or if it has less centre control and king safety. At a human level however, if we get ourselves in a position where we’re so far behind in development that we have to now find 10 ‘only moves’ in a row in order to survive then clearly we’ve gotten ourselves into a bad position. Beginners need to be cautious evaluating their games with an engine as it can be pretty harmful for their chess development as there are a lot of other way the engine can mislead them about what good chess looks like. Better to find a friend who’s a stronger player, join a club or get a coach.

"I don't understand the purpose of that move." ++ It has no purpose.

"disparages a similar move and stresses the advantages of controlling the center" ++ Yes

"h4 is good. It is a fair move" ++ White can afford it.

"What would be the reason for such a move?" ++ None really.

Alex, it is.. Glad to see the others agree with me and not accept review engine comments as gospel. Thanks, everyone!

Very true. I've done it myself.

Fun fact: those comments have almost nothing to do with the engine. Game Review is chess.com's own invention, only loosely (very loosely) based on engine evaluation.
