+title: Clean comparison operator `$x == true` => `$x`
+tags: [good-practice]
+---
+
+Assignment inside a condition like this `$x = false` is usually accidental, this is likely meant to be a `$x`.
+
+```grit
+language java
+
+`$var == true` => `$var` where {
+	  $var <: within `if ($cond) { $body }`,
+	  $var <: within $cond,
+	}
+```
+
+## $x = true
+
+```java
+class Bar {
+    void main() {
+        boolean myBoolean;
+        if (myBoolean == true) {
+            continue;
+        }
+    }
+}
+```
+
+```java
+class Bar {
+    void main() {
+        boolean myBoolean;
+        if (myBoolean) {
+            continue;
+        }
+    }
+}
