``javascript
var features = turf.featureCollection([
turf.point([-97.522259, 35.4691], {value: 10}),
turf.point([-97.502754, 35.463455], {value: 3}),
turf.point([-97.508269, 35.463245], {value: 5})
]);

var options = {weight: "value"}
var mean = turf.centerMean(features, options);

//addToMap
var addToMap = [features, mean]
mean.properties['marker-size'] = 'large';
mean.properties['marker-color'] = '#000';
`

Returns [Feature][1]<[Point][6]> a Point feature at the mean center point of all input features
