Explain what problems it can solve for the audience.

So this code is a simpler way to achieve the same thing: Most of the time, you can use React.PureComponent instead of writing your own shouldComponentUpdate. This section is only relevant if you configure webpack directly. For C1 and C3, shouldComponentUpdate returned true, so React had to go down to the leaves and check them. The model, besides holding the properties described above, provides the API for changing the document and its markers, too. The view may need to be changed manually if the cause of such change is not represented in the model. Conclude your talk by thanking the audience for their time and invite them to ask any questions they may have. Still, this should help you realize when unrelated UI gets updated by mistake, and how deep and how often your UI updates occur.

Let’s again take a look at the editing engine’s architecture: So far, we talked about the topmost layer of this diagram — the model. In many cases it’s not a problem, but if the slowdown is noticeable, you can speed all of this up by overriding the lifecycle function shouldComponentUpdate, which is triggered before the re-rendering process starts. Regardless of what that goal is, be sure to summarise your main points and their implications. You can read about the CKEditor 5 standard UI framework and UI library in the UI library guide. You can add your own observer (which should be a subclass of Observer) by using the view.addObserver() method. In this type of story you launch right into the action by providing a snippet/teaser of what's happening and then you start explaining the events that led to that event. We will explain the conversion later in this guide. You shouldn’t pass the -p flag or apply this plugin in development, because it will hide useful React warnings and make the builds much slower. The font size should be a minimum of 30pt because the audience reads faster than you talk so less information on the slides means that there is less chance of the audience being distracted. It takes place in the “editing pipeline” (the left branch of the diagram). The semantics of HTML is defined in its specification.

If you’re using Create React App, please follow the instructions above. For the most efficient Browserify production build, install a few plugins: To create a production build, make sure that you add these transforms (the order matters): Remember that you only need to do this for production builds. It starts in the top right-hand corner and goes down to the bottom right-hand corner. This representation is called the Document Object Model, or DOM for short. Instead, it’s because they know how to structure presentations - they have crafted their message in a logical and simple way that has allowed the audience can keep up with them and take away key messages. by introducing text attributes), the view is much closer to the DOM. If your component got more complex, you could use a similar pattern of doing a “shallow comparison” between all the fields of props and state to determine if the component should update. These warnings are very useful in development. What should they understand from this?" Indexes relate to nodes (elements and text nodes) while offsets relate to positions. React builds and maintains an internal representation of the rendered UI. A batch may be understood as a single undo step.

In order to create a safer and more useful abstraction over native DOM events, the view implements the concept of observers. virtual-dom is a collection of modules designed to provide a declarative way … The model’s schema defines several aspects of how the model should look: This information is then used by the features and the engine to make decisions on how to process the model. Use logos and pathos for this - the logical and emotional appeals. This is totally fine, but it is still best to focus on delivering some sort of initial presentation to set the tone and topics for discussion in the Q&A. State your presentation's purpose - this is the basis of your presentation so ensure that you provide a statement explaining how the topic will be treated, for example, "I will argue that…" or maybe you will "compare", "analyse", "evaluate", "describe" etc. For each one, SCU indicates what shouldComponentUpdate returned, and vDOMEq indicates whether the rendered React elements were equivalent. That’s ten times more work than necessary! Then the changes you apply to the model are converted (conversion is covered below) to the view by specific converters. They provide several reusable components for displaying lists, grids, and tabular data. Unfortunately, it is also a lot slower than most JavaScript operations.This slowness is made worse by the fact that most JavaScript frameworks update the DOM much more than they have to.As an example, let’s say that you have a list that contains ten items. To handle that, the selection also has attributes. When they are not equal, React will update the DOM. On the other hand, offset x in translates to: The engine also defines three levels of classes that operate on offsets: Markers are perfect for storing and maintaining additional data related to portions of the document such as comments or selections of other users.
