将返回的JSON对象属性转换为（最低优先级）camelCase

这是一个可靠的递归函数，它将适当地驼峰化所有Javascript对象的属性：

function toCamel(o) {  var newO, origKey, newKey, value  if (o instanceof Array) {    return o.map(function(value) {        if (typeof value === "object") {          value = toCamel(value)        }        return value    })  } else {    newO = {}    for (origKey in o) {      if (o.hasOwnProperty(origKey)) {        newKey = (origKey.charAt(0).toLowerCase() + origKey.slice(1) || origKey).toString()        value = o[origKey]        if (value instanceof Array || (value !== null && value.constructor === Object)) {          value = toCamel(value)        }        newO[newKey] = value      }    }  }  return newO}

测试：

var obj = {  'FirstName': 'John',  'LastName': 'Smith',  'BirthDate': new Date(),  'ArrayTest': ['one', 'TWO', 3],  'ThisKey': {    'This-Sub-Key': 42  }}console.log(JSON.stringify(toCamel(obj)))

输出：

{    "firstName":"John",    "lastName":"Smith",    "birthDate":"2017-02-13T19:02:09.708Z",    "arrayTest": [        "one",         "TWO",         3    ],    "thisKey":{        "this-Sub-Key":42    }}
