### Preparing Marker Data for Yandex Maps v3 Clusterer - JavaScript
Source: https://www.npmjs.com/package/@yandex/ymaps3-clusterer?activeTab=readme/package/@yandex/ymaps3-clusterer
This snippet imports React hooks useCallback and useMemo (though only useMemo is used in the subsequent snippet, useCallback is imported here). It defines an array of geographical coordinates and then transforms this array into an array of GeoJSON-like Feature objects, which is the format expected by the Yandex Maps v3 clusterer.
```JavaScript
const {useCallback, useMemo} = React;
const coordinates = [
[54.64, 25.76],
[54.63, 25.7],
[54.43, 25.69],
[54.47, 25.68],
[54.53, 25.6],
[54.59, 25.71],
[54.5, 25.63],
[54.42, 25.57],
[54.12, 25.57],
[54.32, 25.57]
];
const points = coordinates.map((lnglat, i) => ({
type: 'Feature',
id: i,
geometry: {coordinates: lnglat},
properties: {name: 'Point of issue of orders'}
}));
```

### Preparing Feature Data for Yandex Maps Clusterer (JavaScript)
Source: https://www.npmjs.com/package/@yandex/ymaps3-clusterer?activeTab=readme/package/@yandex/ymaps3-clusterer
Defines an array of coordinate pairs and then maps these coordinates into an array of objects formatted as GeoJSON-like 'Feature' objects, which is the required input structure for the clusterer's features property.
```JavaScript
const coordinates = [
[54.64, 25.76],
[54.63, 25.7],
[54.43, 25.69],
[54.42, 25.127],
[54.12, 25.437]
];
const points = coordinates.map((lnglat, i) => ({
type: 'Feature',
id: i,
geometry: {coordinates: lnglat},
properties: {name: 'Point of issue of orders'}
}));

### Defining Cluster Render Function for Yandex Maps v3 Clusterer - JavaScript
Source: https://www.npmjs.com/package/@yandex/ymaps3-clusterer?activeTab=readme/package/@yandex/ymaps3-clusterer
This snippet defines a memoized callback function (cluster) using useCallback. This function is responsible for rendering the visual representation of a cluster. It receives the cluster's coordinates and the array of features it contains, returning a YMapMarker component styled as a circle that displays the count of features within the cluster.
```JavaScript
const cluster = useCallback(
(coordinates, features) => (
),
[]
);
```

### Configuring Grid Clustering Method for Yandex Maps v3 Clusterer - JavaScript
Source: https://www.npmjs.com/package/@yandex/ymaps3-clusterer?activeTab=readme/package/@yandex/ymaps3-clusterer
Inside a React functional component (App), this snippet uses the useMemo hook to create and memoize a clustering method based on a grid. It calls clusterByGrid from the clusterer package, providing a gridSize of 64 pixels to define the size of the grid cells used for clustering.
```JavaScript
function App() {
const gridSizedMethod = useMemo(() => clusterByGrid({gridSize: 64}), []);
// ...
}

### Creating Yandex Map Cluster Rendering Function (JavaScript)
Source: https://www.npmjs.com/package/@yandex/ymaps3-clusterer?activeTab=readme/package/@yandex/ymaps3-clusterer
Defines a function `cluster` that takes coordinates and features and returns a `ymaps3.YMapMarker` instance representing a cluster. It uses a helper function `circle` to create the HTML content for the cluster marker, displaying the count of features within the cluster.
```JavaScript
const cluster = (coordinates, features) =>
new ymaps3.YMapMarker(
{
coordinates,
source: 'my-source'
},
circle(features.length).cloneNode(true)
);
function circle(count) {
const circle = document.createElement('div');
circle.classList.add('circle');
circle.innerHTML = `
${count}
`;
return circle;
}

Source: https://www.npmjs.com/package/@yandex/ymaps3-clusterer?activeTab=readme/package/@yandex/ymaps3-clusterer
This snippet defines a memoized callback function (marker) using useCallback. This function is designed to render individual, non-clustered markers. It receives a feature object and returns a YMapMarker React component, positioning it using the feature's coordinates and including an
