+title: product
+description: Perform a Cartesian product of arrays
+---
+
+### Usage
+
+Creates an array of all possible combinations (Cartesian product) from the given arrays, where each combination is represented as an array (or tuple) of elements.
+
+```ts
+import * as _ from 'radashi'
+
+const colors = ['red', 'blue']
+const sizes = ['big', 'small']
+const compliments = ['nice', 'great']
+
+_.product([colors, sizes, numbers])
+// => [
+//   ['red', 'big', 'nice'],
+//   ['red', 'big', 'great'],
+//   ['red', 'small', 'nice'],
+//   ['red', 'small', 'great'],
+//   ['blue', 'big', 'nice'],
+//   ['blue', 'big', 'great'],
+//   ['blue', 'small', 'nice'],
+//   ['blue', 'small', 'great']
+// ]
