```html
<button
  class="inc"
>
  1
</button>
<div>
  Marko 2
</div>

<button
  id="class-api"
>
  0
</button>
<div
  id="tags-api"
>
  0
</div>
```

### Finalizing Runtime State

Source: https://github.com/marko-js/marko/blob/main/packages/runtime-tags/src/__tests__/fixtures/lazy-tag-nested-async/__snapshots__/writes.debug.html

Completes the runtime setup by pushing final render instructions for both 'grand-child.marko' and 'child.marko' components.

```javascript
M._.b[ "ready:packages/runtime-tags/src/__tests__/fixtures/lazy-tag-nested-async/grand-child.marko" ].push( "packages/runtime-tags/src/__tests__/fixtures/lazy-tag-nested-async/grand-child.marko_0 4" ); M._.b[ "ready:packages/runtime-tags/src/__tests__/fixtures/lazy-tag-nested-async/child.marko" ].push( "packages/runtime-tags/src/__tests__/fixtures/lazy-tag-nested-async/child.marko_0 2" ); M._.w()
```

### WALKER_RUNTIME Initialization

Source: https://github.com/marko-js/marko/blob/main/packages/runtime-tags/src/__tests__/fixtures/counter-intersection/__snapshots__/writes.debug.html

Initializes WALKER_RUNTIME with specific configurations for testing. This setup is used for debugging and snapshotting runtime behavior.

```javascript
WALKER_RUNTIME("M")("_"); M._.r = [_ => [1, { a: 0, b: 0 }], "packages/runtime-tags/src/__tests__/fixtures/counter-intersection/template.marko_0 1"]; M._.w()

Initializes the WALKER_RUNTIME with specific data for a counter multiplier. This setup is used for testing write operations.

```javascript
WALKER_RUNTIME("M")("\_"); M._.r = [_, { e: 0, f: 1 }, "a0 1"]; M._.w()
```

--------------------------------

### Marko Runtime Initialization and Definition

This snippet shows the initialization of the Marko runtime and the definition of a component or tag. It includes the runtime setup and the definition of the component's rendering logic, which involves a closure and element referencing.

```javascript
WALKER_RUNTIME("M")("_"); M._.r = [_ => [2, { input_message: "hello", _: _(1) }], "packages/runtime-tags/src/__tests__/fixtures/known-define-tag-empty-section-fn-closure-element-reference/template.marko_1_input_message 2"]; M._.w()
```

--------------------------------

### Initialize WALKER Runtime

Source: https://github.com/marko-js/marko/blob/main/packages/runtime-tags/src/__tests__/fixtures/at-tags-dynamic/__snapshots__/writes.html

Initializes the walker runtime with specific configurations. This is typically part of the Marko runtime setup.

```javascript
WALKER_RUNTIME("M")("_"); M._.r = ["b0 3 5 7 b1 11 13 b2 9 b1 17 19 b2 15 b1 23 b2 21"]; M._.w()

### Render Dynamic Attributes SSR

Source: https://github.com/marko-js/marko/blob/main/packages/runtime-tags/src/__tests__/fixtures/update-dynamic-attrs/__snapshots__/render-ssr.debug.md

Shows how dynamic attributes are rendered on the server. This example renders static attributes that are then updated.

```html
<div
  a="1"
  b="2"
/>
<div
  a="1"
  b="2"
/>
<div
  a="0"
  b="2"
/>
```

--------------------------------

### Marko Runtime Initialization and Write

Source: https://github.com/marko-js/marko/blob/main/packages/runtime-tags/src/__tests__/fixtures-interop/interop-basic-tags-to-class/__snapshots__/writes.html

Initializes the Marko runtime with a component definition and performs an initial write operation. This sets up the component's initial state and registers it with the runtime.

```javascript
00 WALKER_RUNTIME("M")("_"); M._.r = [_ => [1, { Dc: _.b, d: 0 }, { m5c: "_0", m5i: { count: 0 } }]]; M._.w(); $MC = (window.$MC || []).concat({ "p": "_", "w": [ ["_0", 0, 2, { "f": 1 }] ], "t": ["b"] }); M._.r.push("$C_s 2 a0 1"); M._.w()
```
