+### Partial2 -> Partial5
+
+Returns new function that, when called, has its first argument set to the provided value.
+
+```go
+add := func(x, y, z int) int { return x + y + z }
+f := lo.Partial2(add, 42)
+
+f(10, 5)
+// 57
+
+f(42, -4)
+// 80
+```
+
 ### Attempt
 
 Invokes a function N times until it returns valid output. Returning either the caught error or nil. When first argument is less than `1`, the function runs until a successful response is returned.
