What is a street in poker and how does it impact the flow of the game?

In Poker, a street refers to each round of betting. There are four streets in a typical game: preflop, flop, turn, and river. Each street impacts the flow of the game by introducing new community cards and opportunities for players to bet, raise, or fold. This progression of streets adds complexity and strategy to the game as players must make decisions based on the cards revealed and the actions of their opponents.
