+### curryRight2
+
+Curry a function from the right – split its parameters into 2 lists. Apply the second list of parameters first, without changing the order within the lists.
+
+```js
+const curryRight2 = require('1-liners/curryRight2');
+
+const g = (a, b, c, d) => a + b * c - d;
+g(1, 2, 3, 4);  // => 3
+
+const gλ = curryRight2(g);
+gλ(4)(1, 2, 3);  // => 3
+gλ(3, 4)(1, 2);  // => 3
+gλ(2, 3, 4)(1);  // => 3
+```
+
 ### uncurry2,3,4
 
 Uncurry a function – collapse 2, 3 or 4 lists of parameters into one.
