 [-122.584762, 45.60491],
 [-122.584762, 45.48565],
 [-122.801742, 45.48565]
]]);
poly1.properties.fill = '#0f0';
var poly2 = turf.polygon([[
 [-122.520217, 45.535693],
 [-122.64038, 45.553967],
 [-122.720031, 45.526554],

]]);
poly2.properties.fill = '#00f';
var polygons = turf.featurecollection([poly1, poly2]);

var intersection = turf.intersect(poly1, poly2);
