+title: if else Statements
+---
+## Introduction
+
+The `if` statement executes a statement if a specified condition is **true**. If the condition is **false**, another statement can be executed using the `else` statement..
+
+**Note:** The `else` statement is optional.
+```Go
+  x := 7
+  if x%2 == 0 {
+    // This statement is executed if x is even
+  } else {
+    // This statement is executed if x is odd
+  }
+```
+
+
+Multiple `if...else` statements can be nested to create an `else if` clause.
+```go
+  x := 7
+  if x == 2 {
+    // this statement is executed if x is 2
+  } else if x == 4 {
+    // this statement is executed if x is 4
+  } else if x == 7 {
+    // this statement is executed if x is 7
+  } else {
+    // this statement is executed if none of the aboves is true
+  }
+```
+
+
+In Go you can precede an `if` condition with a statement. The containing variable definition is then valid for the complete `if` block.
+```go
+  if x := 3; x == 2 {
+    // this statement is executed if x is 2
+  } else if x == 3 {
+    // this statement is executed if x is 3
+  } else {
+    // this statement is executed if none of the aboves is true
+  }
+```
