What is React?
When it comes to the world of programming, it seems like there are frequently new programming languages and tools to learn about. One such tool that you should consider is known as React.
Why Should I Learn React?
React can come in and cut this down, while still getting the same work done. This makes it easier to complete your coding while also cutting out some of the waste that may confuse beginners.
The Learning Curve with React
The good news is that when it comes to using React, the learning curve is shallow. This makes it perfect for beginners who worry that everything may be too hard. You can work with the ES6 syntax to make it easier to handle the smaller apps you want to create.
Things to Know About React
React Uses a Virtual DOM
One thing that is different when using React is that it works with a virtual DOM, rather than an actual DOM. The virtual DOM will utilize differential algorithms to get all necessary calculations. This is a good thing because it frees up time and space for the real DOM to process other essential tasks.
We can see how this works with an example. Let’s say that you have a project with 10,000 nodes in it, but you only want to focus on two of those. A lot of processing can be wasted if you try to transverse with all of the nodes for just 2 of them.
With React, you would have the calculations get done by the virtual DOM. This frees up some processing power so the real DOM can jump in, find the two nodes you want to work on, and brings them straight to you.
However, if we bring in that virtual DOM from before with the use of React, we can cut down on some of the delays.The virtual DOM will handle all the data coming in, while the real DOM can present the necessary information to the user.
React itself is not a framework. This means that you can add and take away features based on your own needs. This is why many applications that are built on React are light-weight. You can build up any program or website you want and only pick the features you need.
Many programmers add in Webpack because it offers several plugins that will help to minimize the size of your site. This makes it easier for the application to work correctly, no matter who uses it.
At some point, you will work on your code and hit a roadblock. It could be simple, and you need to add a missing bracket. Or it could be more complicated and include something like a segmentation fault.
No matter what the case is, the earlier you can catch this issue, the easier it is to fix it. This is where React will come in. It will use compile-time debugging so you can find all errors early on. This will help you catch mistakes before they show up at run-time. When this works properly, and you fix the issues, your application and website will run each time entirely.
