Fixing friends’ websites, and then being hired out as a consultant. As my skills or ability to fake-my-skills improved, I sought out consulting gigs. I continued with more articles, books, and online courses. I started by reading articles and seeking advice from friends. My path was convoluted, stressful, and inefficient. I wrote this book for the “me,” five years ago for the person who is starting to think about what it might take to become a programmer or web developer. All I knew was, I wanted to work on computers because I was decent at using them, and I was attracted to the job opportunities. In all honesty, I wasn’t even sure what it meant to work as a web developer. Not until I was in my early thirties did I seriously consider building up skills as a web developer. □ Hi! I’m Angel, the author of the book. We are going to change this to "200px" to help give the turtle a bit of a head start (200px head start to be exact). Again, we won't go into syntax details here.īy setting the turtle's starting position and CSS unit "0px", the turtle is starting on the left-hand side of the screen. This snippet of JavaScript is essentially grabbing the turtle image and assigning it a starting position. Next, in your text editor, navigate to row 69. By making this number lower, to 100 milliseconds, we speed up the race because JavaScript is now changing the positions every 0.1 seconds instead of every 0.5 seconds. Remember to save your changes, and then refresh the browser window.ĥ00 here means 500 milliseconds between each time JavaScript changes the position of the rabbit and the turtle. We are going to change the "speed" of the race by changing a value here. Next, in your text editor, navigate to row 72. With CSS, this was called an Internal Stylesheet, and we did this by adding CSS in the element.įor JavaScript, instead of using the element, we use the element. Similar to CSS, you can add JavaScript on an HTML file by inserting it between a special HTML element. Go ahead and in your text editor, open the "js-example.html" file. Not on how it is doing it or how it is written. My hope is to have you focus on what the JavaScript is doing. You will be changing the JavaScript, but I will not stop to explain the syntax. Next, I'm going to have you change some values on the JavaScript written on the "js-example.html" file.If at any point the race annoys you or you can no longer see the animals, restart and/or stop the animation using the buttons. This is an example of what interactivity looks like. The "racing" between the turtle and rabbit, as well as the buttons "stopping" and "restarting" the race, are all done by JavaScript.Play around with stopping and restarting the animation. The turtle □ and rabbit □ will start racing right away. Once open, you should see a web page that looks something like the following: Because this HTML file uses two images, you need to download the following folder, and then right-click to open the "js-example.html" file in Chrome.What do I mean when I say "JavaScript makes that structure (HTML) interactive"? To help answer that question, I've created an HTML file that uses JavaScript to add interactivity in the form of a turtle □ and rabbit □ racing each other.
