Why is data at the front in vue?

The reason why the data attribute is placed at the front in Vue
data in Vue.js
Properties are usually placed in the first position of the component because it is the core of storing data inside the component.
Main reason:
-
The first task of component initialization: The component needs to initialize its state when it is created,
data
Attributes are used to save this initial state. Placingdata
first ensures that the component's data is set before initializing it. -
Conventions from other libraries like React and Preact: Vue.js borrows best practices from other libraries like React and Preact, where the
data
attribute is also at the front . This helps keep your coding style consistent and readable. -
Clear and unambiguous code structure: By placing
data
at the front, it is separated from other component properties such asmethods
,computed
) are clearly separated to make the code structure clearer and easier to understand. -
Avoid unintended side effects: If the
data
property is not placed first, it may cause unexpected behavior for other data-dependent state properties. By putting it first, you ensure that the component initializes reliably in all situations. -
Convenience for debugging: Putting the
data
attribute first can make the debugging process easier. Developers can quickly identify and access a component's initial state, which helps isolate and resolve problems.
