JavaScript partial functions

Use closures to create functions with pre-filled certain parameters.
Javascript code

  
 function jionWords(a, b){  
   return [a, b].jion(' ');  
    }  
  
 function prefixer(word){  
   return function(b){  
     return jionWords(word, b);  
   }  
 }  
  
 var hate = prefixer('Hate');  
  
 hate('Java'); //返回值为:Hate Java

It can be seen that you can use this to create a function with a dynamic name. It should look awesome and the code will be more readable.
