The child component then calls it,passingprops as arguments. To implement named slots using render functions, you'll typically work with the `createElement` (often aliased as `h`) functionRemember, the element renders out content that's passed to the component as aslot. So we're taking that content from Parent and thenrenderingit  This function is the backbone of Vue's rendering process, generating VNodes (Virtual Nodes) that represent the component's structureVue Tips — Slots, Vue Router, and Mutations - Dev Genius

When defining a component that accepts slots via render functions, you need a mechanism to expose these slots to the parentRender Functions Explained - Senior Vue.js Developer Exam Vue provides the `scopedSlots` property within the data object passed to `createElement`A Practical Use-Case of Render Functions in Vue This is where the magic happens for passing named slotsPassing a function to a child component slot in Vue 2.5? You can define an object where keys represent the names of your slots, and values are functions that return the VNodes for that specific slot's content[VUE 2] Vue component slots in cells

For instance, consider a scenario where you have a `BaseLayout` component designed to accept a header and content via named slotsVue.js Scoped Slots and Render Functions In its render function, you would structure it like this:

```javascript

// Inside the render function of your BaseLayout component

createElement('div', {

However, when using render functions to *pass* content *to* named slots in a child component, the approach is slightly differentRemember, the element renders out content that's passed to the component as aslot. So we're taking that content from Parent and thenrenderingit  The parent component's render function will invoke the child component and pass the slot content as the third argument to `createElement`Can you use scoped slots with render functions? #9544 For named slots, this is done by providing an object where keys are the slot names and values are the VNodes for the content to be renderedSlots | Vue Test Utils

Let's illustrate with a parent component passing content to a `FancyCard` component which expects a `title` and `actions` named slot:

```javascript

// Parent component's render function

render(h => {

return h('FancyCard', {

// Props for FancyCard go here

}, {

// Defining named slots

title: h('h1', 'My Awesome Title'),

actions: h('button', 'Click Me')

});

});

```

It's also important to note the distinction between regular slots and scoped slotsRender Functions and JSX in Vue.js Development Scoped slots go a step further by allowing the child component to pass data back up to the parent2020726—Alternatively, we can userender function to pass down the slots. For instance, we can write render(h) { const children = Object.keys(this  When working with scoped slots and render functions, the structure within the `scopedSlots` object in the child component becomes a function that receives the props from the child:

```javascript

// Child component's render function (e2020216—This time we use theslot-scope attribute and assign thenameslotProps to it. Inside this scopedslotwe can access all props passed along via gHow to Use Nested Slots in Vue (including scoped slots), a UserProfile)

// Scoped slot for additional details

h('UserProfileDetails', {

}

})

]);

});

```

In the parent component, you would then consume this scoped slot using the `slot-scope` attribute (in Vue 2) or the `v-slot` directive with a scope variable (in Vue 3):

```vue

{{ slotPropsThe custom component I'm using has a defaultslot. Is it possible topassdata to thisslotin the rendererfunction? User avatar age }}

```

When using render functions for the parent, you'd pass `scopedSlots` to the child component's `createElement` call, similar to how you pass regular slots but with the function structure to receive propsA Practical Use-Case of Render Functions in Vue

A common pattern involves using render functions to pass down the slots from a wrapper componentVue Tips — Slots, Vue Router, and Mutations - Dev Genius For example, a `BaseButton` component might use a render function to create an `` tag or a `` internally while accepting slot content for its labelUnderstanding slots in Vue.js Types, benefits, use cases
