What is the provide/inject feature in Vue.js?

Can you explain the provide/inject feature in Vue.js?

Sure! The provide/inject feature in Vue.js allows you to pass data from a parent component to deeply nested child components without having to pass props through every level.

How does it differ from props?

Unlike props, which require you to pass data through each component in the hierarchy, provide/inject allows for a more direct way to share data across components.

Can you give me a code example?

Absolutely! Here's a simple example:

// Parent Component
export default {
  provide() {
    return { message: 'Hello from parent!' };
  }
};

// Child Component
export default {
  inject: ['message'],
  mounted() {
    console.log(this.message); // Outputs: Hello from parent!
  }
};

Are there any limitations to using provide/inject?

Yes, provide/inject does not reactively track changes to the provided data, so if the parent updates the data, the child won't automatically receive the new value unless you use a reactive object.
