This article mainly introduces that data in vue should always return a function, which has certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let Xiaobian take you to understand it together.

data should always return a function

When declaring the component data, the data option should always return a function. If an object is returned, the data is shared among all instances of the component.

//bad practice data: { name: 'My Window', articles: []}

However, in most cases, our goal is to build reusable components, so we want each component to return a unique object. We do this by returning data objects in functions.

//good practice data () { return { name: 'My Window', articles: [] }} Thank you for reading this article carefully. I hope that the article "data in vue should always return a function" shared by Xiaobian will be helpful to everyone. At the same time, I hope everyone will support it a lot.
