+## Usage
+
+```javascript
+var forEachGraphemeCluster = require( '@stdlib/string/base/for-each-grapheme-cluster' );
+```
+
+#### forEachGraphemeCluster( str, clbk\[, thisArg ] )
+
+Invokes a function for each grapheme cluster (i.e., user-perceived character) in a string.
+
+```javascript
+function log( value, index ) {
+    console.log( '%d: %s', index, value );
+}
+
+forEachGraphemeCluster( 'Beep!', log );
+/* =>
+    0: B
+    1: e
+    2: e
+    3: p
+    4: !
+*/
+```
+
+The invoked function is provided three arguments:
+
+-   **value**: grapheme cluster.
+-   **index**: starting grapheme cluster index.
+-   **str**: input string.
+
+To set the function execution context, provide a `thisArg`.
+
+```javascript
+function clbk() {
+    this.count += 1;
+}
+
+var str = 'Hello, world!';
+
+var ctx = {
+    'count': 0
+};
+
+forEachGraphemeCluster( str, clbk, ctx );
+
+var bool = ( str.length === ctx.count );
+// returns true
