We all like building a fun project and one of them is a simple game. today I will be building a rock paper scissors game with `RPSjs` library which I built myself a year ago. the whole source code is at the [end](#code). this is how it will look ![Desktop-screenshot](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/co41n7fu22fkpwq0c7zj.png) when you click the buttons it shows what the computer choose against yours and who won ![7cd19c054f22a60646f87ce541e422b1152def5b](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ir7mbmeunkmg5n0mvbej.gif) you can play with this [JSfiddle](https://jsfiddle.net/bethropolis/fdvxLk13/5/) # first we will import the library through a CDN ```html ``` you can visit the website for the [documentation](https://bethropolis.github.io/rockPaperScissorsjs) or [Github](https://github.com/bethropolis/rockPaperScissorsjs) we are going to create a boilerplate ![xdfsghh-svg](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/hxlcedde1rxdf9zlbqno.png) where are now going to add the buttons ![gy8oooo-svg](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/sr9cjuny1q7n4hll4tz3.png) > add the cdn onto the `` ![half-svg](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/dohs8iayih4bkd6be4f0.png) # javascript now it is time for sweet JavaScript to be added. ![oggggui-svg](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/awckayevg23ye838nilw.png) ## explanation ```js document.querySelectorAll("button").forEach(btn =>{ btn.addEventListener('click',function(){ startGame(btn.innerText) }) }) ``` in the Js, we first get how many buttons are on the document with the `document.querySelectorAll("button")` and for each button, we add an event listener which will call the `startGame()` function when clicked. the `btn.innerText` is passed as a parameter in the function which will be the user's choice. For example, if you click ` ``` and there you go, you have your very own rock paper scissors game. ![huraaay](https://media.giphy.com/media/TdfyKrN7HGTIY/giphy.gif) # about I am Bethuel and this is my first post, I hope you enjoyed it and thanks for sticking by.
