Now you need to store the randomly generated number so that you can compare it to your player's guesses. Voila! Now you have a (somewhat) randomly generated number between 1 and 100: Math. You can fix that with your last step, which is to add 1 to the result. That leaves you with a whole number between 0 and 99, which isn't quite the range you want. Math.floor()'s purpose is to return the largest integer that is less than or equal to the number you give it as an argument-which means it rounds down to the nearest whole number: Math. For that, you can use another function that is part of the Math object, Math.floor(). Right now, your number is still a decimal, and you want it to be a whole number. But you'll take care of that in a few more steps. Take the decimal you just generated and multiply it by 100 to produce a decimal between 0 and…not quite 100. This means that the function could generate a zero, but it will never generate a 1.)įor this game, set the random number between 1 and 100 to narrow down the player's options. (Math.random is inclusive of 0 but exclusive of 1. Start with Math.random(), which generates a pseudo-random number between 0 and 1. You will use two Math functions to generate the random number for your player to guess.
Math has properties and functions for working with mathematical concepts in JavaScript. To generate your random number, use the Math object. JavaScript includes several built-in global objects that help you write code. The first step in the guessing game is to generate a number for the player to guess.
(If you are using Brackets, you can also use the lightning-bolt symbol in the corner to open the file in the browser). To run this in the browser, either double-click on the file or go to the menu in your favorite web browser and choose File > Open File. The final file looks like this:Ĭonst randomNumber = Math.floor(Math.random() * 100) + 1Ĭonsole.log('Random Number', randomNumber)įeedback.textContent = "You got it right!"įeedback.textContent = "Your guess was " + myGuess + ". Now, you can start to write your JavaScript between these two script tags. Those tags should go right before the closing tag near the end of the HTML file. There are many ways to include JavaScript in a web page, but for a short script like this one, you can use a set of tags and write the JavaScript directly in the HTML file.

The empty set of tags at the end of this code block serve as a placeholder for the feedback the game will give the player based on their guess. The set of tags that follow signify that the short block of text with the instructions is a paragraph. The set of tags signifies that the text between those two tags ( Guess the Number!) is a heading. The and elements let the browser know what type of text to display on the page. I am thinking of a number between 1 and 100.

Use a few basic HTML tags in this file to display the game's title, instructions for how to play, interactive elements for the player to use to enter and submit their guesses, and a placeholder for providing feedback to the player: You can call your file guessingGame.html. html extension to let the browser know that it is an HTML document. To start, create an HTML file for your code. In case you aren't familiar, HTML is a markup language used to provide structure to content on the web. To create this game, you'll first use HTML (Hypertext Markup Language) to create a simple interface for your players to use. JavaScript runs in a web browser and interacts with the other standard web technologies, HTML and CSS. All you need is a code editor ( Brackets is a great one to try) and the web browser of your choice. JavaScript comes in many flavors, but I'll start with the basic version, commonly called "Vanilla JavaScript." JavaScript is primarily a client-side scripting language, so it can run in any standard browser without installing anything.
