However, React JS creates something called a Virtual DOM. The Virtual DOM as the name implies is a copy of the site’s DOM, and React JS uses this copy to see what parts of the actual DOM need to change when an event happens. Only those parts are updated and the changes are reflected. This kind of selective updating takes less computing power and less loading time, which might not sound like much but when you start to think about all the dynamics and updating associated with even a slightly complex website—you’ll realize it adds up to a lot.
- Basic familiarity with HTML & CSS - Html elements are the building blocks of web pages. CSS controls the style and layout of the web pages
- Installing Django: The easiest and the recommended way to install Django is via pip - Installing an official release with pip. If should be a fairly easy installation but if you face any problems, you could refer to the full installation process over here. You could also refer to the troubleshooting guide over here or you could simply google your problem (which you should always do before asking anyone for help). If you still face problems you could reach out to the Django community (for details on how to reach them, refer to 'Reaching out for help' section below).
- Understanding the Concept: The most crucial and tricky step is understanding the basic idea behind how things co-ordinate between files to make your webpage. This is a 15-20 min short tutorial,The Django Logic which is precise and upto the point to get started. We suggest you to go through this, before starting with your further journey in developing awesome webpages.
- Getting started: What better way to learn Django than from the tutorial which the Django community themselves have created. Apart from creating your very first application on Django you will learn the best practices which is necessary if you want to get the best out of this framework. This is the tutorial -Writing your first Django app . Make sure you complete this. Another tutorial, which I found really helpful is Django Girls Tutorial. The title may be a bit misleading (:P), but trust me, this tutorial is meant for all genders and if you are a complete newbie, this is the tutorial for you. If you are more suited to video lectures you should definitely have a look at this video series by CodingEntrepreneurs - Try Django 1.10. This video series also puts a lot of emphasis on best practices and you will also learn a lot about other development tricks and tools. It's a bit long, so I'd suggest you skip over parts you are already familiar with.
- Becoming a master: After completing the basic tutorials above, if you're hungry for more this section will satisfy you're needs. Developing a full scale Django app for production purposes (when your app goes public and everyone can use it) requires a extra bit of effort. You would have to take care about a lot of things like deployment, security etc. And I believe this tutorial by Marina Mele fully accomplishes this. This is the complete package to become a professional developer. You will learn about security issues, different environments for developing and testing, version control repositories, deployment on Heroku, PostgreSQL configuration, and many more things! This tutorial is a long one and you could skip the things you learnt in the basic tutorials above and focus on what you really want to learn. Overall this is a very comprehensive tutorial and you will understand what is takes to take your product from development phase to production phase.
- Reaching out for help: The Django community is one of the most open and helpful. You could easily ask your doubts on their official gitter channel - django/django. You could even use their google groups - django-users mailing list, to ask questions about how to use Django. For more information on how to contact them, you could refer to their contact us page here. But remember one thing, just because they are helpful it doesn't mean we try to take advantage of them. Make sure you research your problem well and only if you're sure it's worth asking, then only post your doubt. It's never good to take anything for granted.
I hope you had a good time learning about Django and we hope we have convinced you that if you are thinking about web development learning Django is a good step forward. Even if you want to just start with developing anything but you aren't really sure which direction to do, learning Django would still be a good step forward. The strong focus on good developing principles, great documentation and community are all necessary if you want to be a good developer. We also hope that we have pointed you in the right direction to learn Django and all the tutorials linked over here were helpful to you. You are most welcome to correct any kind of errors you find in this article. Cheers!
