+## Page 8 - Fixing the equals syntax in an `if` statement
+
+The example of an `if` statement here explains how a single `=` sign is always true. It should be `if(hobby = "coding")`
+
+Incorrect code is:
+```
+if(hobby == "coding"){
+console.log("** I love coding too! **");
+} else {
+console.log("** Can you teach me that? **");
+}
+```
+Correct code is:
+```
+if(hobby = "coding"){
+console.log("** I love coding too! **");
+} else {
+console.log("** Can you teach me that? **");
+}
+```
