jQuery.merge()

今天学习seajs，遇到return $.merge(['module1'], $.merge(m2.run(), m3.run()));不明白啥意思，上网查了一下明白了，记录一下

jQuery.merge( first, second ) 返回： Array

描述： 合并两个数组内容到第一个数组。

• version added: 1.0jQuery.merge( first, second )

  first第一个用来合并的数组，元素是第二数组加进来的。

  second第二个数组合并到第一，保持不变。

• Examples:

  Example: Merges two arrays, altering the first argument.

  $.merge( [0,1,2], [2,3,4] )

  Result:

  [0,1,2,2,3,4] 

  Example: Merges two arrays, altering the first argument.

  $.merge( [3,2,1], [4,3,2] )  

  Result:

  [3,2,1,4,3,2] 

  Example: Merges two arrays, but uses a copy, so the original isn't altered.

  var first = ['a','b','c'];
  var second = ['d','e','f'];
  $.merge( $.merge([],first), second);
        

  Result:

  ["a","b","c","d","e","f"]
