+This uses the [*An O(ND) Difference Algorithm and Its Variations*](http://www.xmailserver.org/diff2.pdf)

+
+## Installation
+
+    $ npm install diff
+    $ component install Swatinem/diff
+
+## Usage
+
+### diff(a, b, [eql(a, b)])
+
+Given two arrays (or array-likes, such as strings) `a` and `b` and an optional
+equal function `eql`, this will return an array with the following operations:
+* *nop* the element is in both arrays
+* *ins* the element is only in array `b` and will be inserted
+* *del* the element in only in array `a` and will be removed
+* *rep* the element from `a` will be replaced by the element from `b`.
+This is essentially the same as a del+ins
