+# congruent
+
+Deep comparison of two variables
+
+This is different from [deep-equal](https://github.com/substack/node-deep-equal) in that it will compare
+Buffers, Regular Expressions, and NaN (In my opinion, NaN should equal NaN)
+
+```javascript
+
+var congruent = require('congruent');
+
+congruent([1, 2, 3], new Array(1, 2, 3));
+// true;
+
+congruent(NaN, NaN);
+// true;
+
+congruent({ a: [1, 2, 3] }, { a: [1, 3, 2] });
+// false;
+
+```
+
+## congruent(a, b, strict)
+
+* strict - Use strict comparison (===) between primitives (Boolean, String, Number) (default: false)
+
+## Installation
+
+```bash
+npm install congruent
+```
