+/**
+ * Encode a string to a native JavaScript expression.
+ *
+ * This class simply holds a string with a native JavaScript expression,
+ * so objects or arrays to be encoded with Laminas\Json\Json can contain native
+ * JavaScript expressions.
+ *
+ * Example:
+ *
+ * <code>
+ * $foo = array(
+ *     'integer'  => 9,
+ *     'string'   => 'test string',
+ *     'function' => Laminas\Json\Expr(
+ *         'function () { window.alert("javascript function encoded by Laminas\Json\Json") }'
+ *     ),
+ * );
+ *
+ * echo Laminas\Json\Json::encode($foo, false, ['enableJsonExprFinder' => true]);
+ * </code>
+ *
+ * The above returns the following JSON (formatted for readability):
+ *
+ * <code>
+ * {
+ *   "integer": 9,
+ *   "string": "test string",
+ *   "function": function () {window.alert("javascript function encoded by Laminas\Json\Json")}
+ * }
+ * </code>
