- How To Share React Components between Apps with Bit
- Bit: A powerful tool for efficient sharing of React components This article introduces Bit, an open source tool that can significantly improve the code sharing efficiency between projects, especially React components, with extremely low additional overhead. Developers can use Bit to share parts of the code base and use them in other projects to easily synchronize changes without splitting the code base or modifying the source code structure. The core advantage of Bit is that it decouples the representation of shared code from the file system of the project. This means you can specify the components that Bit wants to share and export them from your project without changing its structure or source code. Once shared, these components can be installed using your favorite package manager and can be modified and updated in any project environment. Bit also

- What's the Difference Between Sass and SCSS?
- Sass and SCSS: Which preprocessor to choose? Core points Sass and SCSS are both preprocessor scripting languages compiled into CSS, but the syntax is different. Sass uses indentation syntax, while SCSS uses CSS-like syntax. This means that Sass does not require semicolons or brackets, while SCSS uses brackets to represent code blocks and separates lines within blocks with semicolons. The choice of Sass and SCSS depends on personal preferences and project needs. However, because SCSS has a similar syntax, SCSS may be easier to get started for beginners or those who are already familiar with CSS. It is also more compatible with existing tools, plugins and demos, which makes it

- Working with Data in React: Properties & State
- React components use two types of data: properties and state. Properties are input values used when rendering components and initializing states, and once components are instantiated, they should be considered immutable. On the other hand, the status data may be changed by the component and is usually connected to the component's event handler. Key Points The React component divides data into immutable properties and variable states to more clearly identify the role of each data and its relationship to the component. Attributes are more popular because they simplify data flow. Status is useful for capturing data updates caused by user interactions and other UI events. The relationship between attributes and states facilitates the flow of data in components. Properties are input values used when rendering components and initializing states.
