+## :book: Introduction  
+PHP's array functions are painful for developers. (like `array_map`, `array_filter`)  
+- Array first or callback function first...  
+- Return value or reference a variable...  
+
+In addition, since it is a `function`, the code breaks every time.  
+I created this library to solve these problems and make code flow like `js-array`.  
+  
+<br>  
+  
+## :zap: Features  
+You can use `ArrayUtils` to use the features of this library.
