Until the flop appears on the table, do not rush to place your bets. This is particularly the case for a player with pocket jacks who is in early position. Playing JJ with an average pair is their objective assessment. Call in this position if only because subsequent players may have shorter cards.
Of course, you can raise, but only if you understand that you are playing with tight players who can fold like AQ, AJ, A10. If you play with aggressors, then all the more hold on to your preflop raises - keep in mind that every preflop bet you make will be supported in the same way as your cbet already on the flop.
A good raise with jacks is from late position. Here, if there were no raises and reraises before you, you already at least have an idea of the potential of your opponents.
