 ## :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...  
+The ~~evil~~ PHP array functions give developers the pain of:
 
-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`.

-## :zap: Features

-## :wrench: Installation
-See [poggit/support/virion](https://github.com/poggit/support/blob/master/virion.md)
+* Some functions **requires array first**, but some functions **require array last**...  
+* Some functions **returns result**, but some functions **modify referenced variables**...
+* Code was **line-break** because since it is a function...
+* Each function has **different parameters to the callback function**...
+* No modern functions using arrays. Such as `every`, `some`
+
+I created this library to solve these problems and make code flow like `js-array`
