+# `intersectByKeys()`
+
+The intersectByKeys method removes any keys from the original collection that are not present in the given `array` or collection:
+
+```js
+const collection = collect({
+  serial: 'UX301',
+  type: 'screen',
+  year: 2009,
+});
+
+const intersect = collection.intersectByKeys({
+  reference: 'UX404',
+  type: 'tab',
+  year: 2011,
+});
+
+intersect.all();
+
+// { type: 'screen', year: 2009 }
+```
+
+```js
+const firstCollection = collect([1, 2, 3, 4, 5]);
+const secondCollection = collect([1, 2, 3, 9]);
+
+intersect = firstCollection.intersect(secondCollection);
+
+intersect.all();
+
+// [1, 2, 3]
+```
