Component split understanding

In Vue, the timing of splitting components can be divided into the following situations:

1. Component reuse: If a component needs to be used in multiple places, then the component should be split out for reuse.
2. Component nesting is too deep: When too many subcomponents are nested inside a component or too many instructions, methods, etc. are used, the code will be difficult to maintain. At this time, it is necessary to disassemble subcomponents according to different functions to achieve the purpose of clear code and easy maintenance.
3. Component Single Responsibility Principle: Each component should only be responsible for one function or business. If a component has too many responsibilities, its code will be bloated and difficult to maintain. Therefore, if a component's responsibilities are too complex, it can be split into multiple components.

In short, when a component becomes larger and more difficult to maintain, or there are multiple reuse requirements, it should be considered to split the component into smaller subcomponents.
