This is a fun and simple way to create a Battleship Game using only JavaScript

var randomloc = Math.floor(Math.random() * 20)

var loc1 =randomloc;

var loc2 = loc1+1;

var loc3 =loc2+1;

var guess;

var hits =0;

var guesses = 0;

var isSunk = false;

while (isSunk == false){

guess = prompt("Ready aim fire! (enter a # from 1-20):");

if (guess<0 || guess > 20){

alert("Please enter a valid cell #!");

}

else {

guesses = guesses +1;

if (guess == loc1 || guess == loc2 || guess== loc3){

alert ("Hit");

hits =hits+1;

if (hits ==3){

isSunk =true;

alert("You sank my battleship!");

}

}else {

alert("miss");

}

var stats = "you took " +guesses+" guesses to sink the battleship,"+"which means your shooting accuracy was "+(3/guesses)+"%";

alert(stats);
