error for feature colletion

[gagan-bansal]

My test data:

var ext = require('geojson-extent'),
featColl ={"type":"FeatureCollection","features":[{"type":"Feature","properties":{"osm_id":243819778,"name":"Port Louis","type":"city","population":147688},"geometry":{"type":"Point","coordinates":[57.5045331,-20.1637281]}}]};
console.log(ext.bboxify(featColl));

and here is the output error:

/mypath/node_modules/geojson-extent/node_modules/geojson-coords/index.js:10
    normalized.features.forEach(function(feature) {
              ^

Or am I doing something wrong?

This is a bug in geojson-extent; it's using the "type" property to guess what things are bbox'able, and since there's type in the properties object, it's trying to find its bbox. I'll need to do a less-lazy traversal of the object.
