+# Prevent declaring unused methods of component class (react/no-unused-class-component-methods)
+
+Warns you if you have defined a method but it is never being used anywhere.
+
+## Rule Details
+
+The following patterns are considered warnings:
+
+```jsx
+class Foo extends React.Component {
+  handleClick() {}
+  render() {
+    return null;
+  }
+}
+```
+
+The following patterns are **not** considered warnings:
+
+```jsx
+class Foo extends React.Component {
+  action() {}
+  componentDidMount() {
+    this.action();
+  }
+  render() {
+    return null;
+  }
+}
+});
+```
