[CodeWars] 8kyu#8 - Shifty Closures

■ Description:

Functional closures can get overly attached. Set them straight!

Why doesn't greet_abe() actually greet Abe?

■ Qustion

var name = 'Abe';
var greet_abe = function() {
  return "Hello, " + name + '!';
};
name = 'Ben';
var greet_ben = function() {
  return "Hello, " + name + '!';
};

■ My Solution

var greet_abe = function() {
  var name = 'Abe';
  return "Hello, " + name + '!';
};
 
var greet_ben = function() {
  var name = 'Ben';
  return "Hello, " + name + '!';
};

아.. 클로저, 

■ Best Solution

var name;
function greet_abe() {
  name = 'Abe';
  return "Hello, " + name + '!';
};
 
 
function greet_ben() {
  name = 'Ben'; 
  return "Hello, " + name + '!';
};
