It is supported in version 2.5.x. While default slots are useful for basic content injection, named slots allow for more precise placement of content within a child componentScoped slots ismore data from the component exposed to the slotbut implemented in the parent. For example, the parent passes rows into a table However, it's the scoped slots that truly unlock advanced customization and data sharing capabilitiesDeeper Understanding About Slots In Vuejs.

Implementation of Default Slot .Vue has a feature called slots, which includes three types default slot, named slot, and scoped slot. This means that instead of the parent simply providing content to the child, the child can provide more data from the component exposed to the slot, which the parent can then leverage to render or control the slotted contentUsing Slots In Vue.js This bidirectional data flow is crucial for building highly flexible and decoupled componentsUsing Slots In Vue.js
The Evolution of Slot Syntax: From `slot-scope` to `v-slot`
Historically, the `slot-scope` attribute was the primary mechanism for working with scoped slotsUsing Scoped Slots in Vue.js to Abstract Functionality It allowed developers to define a variable name in the parent template that would receive the data exposed by the child component's slotHow To Use Scoped Component Slots in Vue.js For instance, a child component might expose a `user` object via its scoped slot, and the parent could access this data using ``: `{{ propsUsing Scoped Slots in Vue.js to Abstract Functionalityuser202345—In Vue.js, slots are a way to pass content to a component.They allow you to define a section of a component's templatethat can be replaced by the parent name }}`202345—In Vue.js, slots are a way to pass content to a component.They allow you to define a section of a component's templatethat can be replaced by the parent
However, the naming of `slot-scope` has been critiqued as potentially misleading, with some developers suggesting that "scope" might not be the most accurate descriptor, especially when compared to concepts like Angular's scope20171222—The current name "slot-scope" is rather misleading because "scope" is the wrong concept to suggest; particularly given Angular's use ofscope. To address this and to unify the syntax for named and default slots, Vue introduced the `v-slot` directive in version 2Slots . Implementation of Default Slot .Vue has a feature called slots, which includes three types default slot, named slot, and scoped slot.6202134—Scoped component slots are a feature introduced in Vue 2.1.0.

Leveraging Scoped Slots for Advanced Component Design
The primary benefit of scoped slots is the ability to allow a child component to pass data from a child component to its parentslot-scope support multiple parameters · Issue #9468 This empowers developers to create highly customizable components where the parent component dictates the presentation of content while the child component manages the underlying data and logicHow to Use Nested Slots in Vue (including scoped slots)
Consider a common use case: a list componentUsing Scoped Slots in Vue.js to Abstract Functionality The child component might fetch and manage an array of items, but it can use scoped slots to allow the parent to define how each individual item is rendered202134—Scoped component slots are a feature introduced in Vue 2.1.0. They allow you to pass properties from your child components into a scoped slot and access them The child component could expose an `item` object to the slot, and the parent could then use this data to display the item's name, image, or any other property using slotsAdvanced Vue.js Component Concepts - Using Scoped Slots This approach, where slots are a mechanism for Vue components to share content beyond strict parent-child relationships, is a cornerstone of building flexible UIsMastering Slots in Vue.js Default, Named, and Scoped Slots

When working with large or complex components, especially in Vue 3 Typescript projects, preserving child slot types is crucial for type safety and developer experience2019613—Scoped slots make it possible to pass data from a child component to its parent, thus allowing complete customization of the content.
