Also, something that I've found is that if you go wrong somewhere instead of mindlessly searching for the error (assuming there are multiple or you don't know the error's location) just start from the beginning and go down seeing that if this works. If you see a break and something disconnects, in all probability that's where the error is. It's all logic.
This Google project for web developers launched in 2010 to counter Apple’s HTML5. The site is full of tutorials, resources and the latest HTML5 updates. It’s open source, so developers can play around with HTML5 code. Because this site's offerings are more advanced than most introductory courses, you'll need some knowledge and experience before jumping in.
I think there’s so much stuff and challenges and quizzes and videos to help, but it gets really confusing sometimes when there’s so much information thrown at you. In the assignments tab I think you should add important key features, viewing the assignments from due earlier to due later, viewing assignments from highest level like 88% on a practice to 100% on a practice and separating them from videos and practices and everything else. It’s really a pain to scroll all the way to the bottom to see my assignments I didn’t complete since my teachers assign a LOT and I mean A LOT of homework on your app. I decided to rate your app fairly and not biased on we’re I like math or not, but rather the methods to teach and learn math. So there are some highlights. I like that you get hints for every single practice and it must be hard to make all of the detailed word problems. I also like that you can look back into the questions you messed up and learn from those questions.
Once you figure out why you want to code, you can more easily pinpoint which programming language you should tackle. While there is no single “best” programming language to learn, some languages are more user-friendly than others. HTML and CSS are considered the easiest entry points into the coding world, but they are only really useful for developing basic websites.
Take a few minutes (or a day) to think about the reasons—the real reasons—why you want to learn a programming language. Be honest with yourself. Are you trying to learn the barest minimum to score a promotion? Are you looking to make a big career change? Do you want to create the next greatest app? Thrill your roommates by programming your various smart devices to do something awesome?
