• KK.each(collection, callback)

  • collection {array | json}
  • callback {function} When callback return false, loop will break.

  var a = [11, 22, 33, 44]
  KK.each(a, function(item, index, context){
    if(item > 22){
      return false;
    }
    // 33 and 44 will not print
    console.log(item);
  })

    var a = 'name=lily&age=2&grade=3';
    // Got {'name' : 'lily', 'age' : 2, grade : 3} 
    KK.queryString(a) 
    
  

• KK.merge(target, source)

  var target = { a : 1, read : {book : true}, count : [11]}
  var source = { a : 2, read : {paper : true, book : false}, count : [1]}
  
  // Got { a : 2, read : {book : false, paper : true}, count : [1] }
  KK.merge(target, source); 
  console.log(target.read === source.read); // true
  

• KK.deepMerge(target, source)

  var target = { a : 1, read : {book : true}, count : [11]}
  var source = { a : 2, read : {paper : true, book : false}, count : [1]}
  
  // Got { a : 2, read : {book : false, paper : true}, count : [1] }
  KK.merge(target, source); 
  console.log(target.read === source.read); // false
