Realised in my original post that I used the wrong terminology but that makes sense. Thanks for this.

Hi All, i'm new to this forum && Javascript. Currently employed as a QA Tester but have an interest in automation testing. As part of extra curricular learning I am starting on Javascript, then checking out Node.js and Selenium.js. As part of a licence obtained through work I am going through some Pluralsight courses. Credits to the author, but I am wondering whether anyone can shed some light on this part of the code. I understand the logic behind the rest, just not this section. <part I do not understand> var survival = randomNumber(2); Notes: Why is the parameter (2) and not () or (0)? Is it because the array has 3 elements and giving a 33% chance? <all the code> // define the scenarios of the game var beginningScenarios = ["You wake up in a hospital, it is quiet. You open the door and peek out...", "You are standing in a field with a house and a boarded up door...", "Desperate times call for desperate measures. You see a small store and decide to loot it for goods..."]; // create a function called randomNumber function randomNumber(range) { return Math.round( Math.random() * range ); } // using the randomNumber alert a scenario alert( beginningScenarios [ randomNumber( beginningScenarios.length -1) ] ); // store weapons to an array var weaponList = ["Shovel", "Crossbow", "Baseball Bat", "Rubber Chicken"]; // randomise the weapons var weapon = weaponList[ randomNumber( weaponList.length - 1 ) ]; alert("Being that is it the apocalypse, you decide to search for a weapon first. After searching some nearby boxes you find a " + weapon + "."); // attack the zombie alert("Suddenly a zombie bursts through the door! You ready your " + weapon + " and advance towards the zombie!"); var survival = randomNumber(2); // result of the attack if (survival === 0){ alert("You swing your " + weapon + " & you miss.") alert("The zombie bites you! Game over"); } else if (survival > 0) { alert("You swing your " + weapon + " & you strike the zombie."); alert("You kill the zombie. You win!"); } Thanks for taking your time to answer my question!
