In this kit, we're going to see how to Guess the Number Game in Reactjs with simple steps.A number guessing game is a simple guessing game where a user is supposed to guess a number between 0 and N in a maximum of 10 attempts. The game will end after 10 attempts and if the player failed to guess the number, and then he loses the game.The game is two-person game called "Guess the Number". The first player thinks of an integer within a known range. The second player tries to guess the number. If the guess is incorrect, then the first player tells the second player whether the guess was too high or too low.
