简单的按照汉字，字母的首字母分组

简单的按照汉字和首字母分组，将数字开头的数据提取出来归类到一起

{letter: '数字开头', data:[]}

//假设一原始数据为 originArr 很常见的用户信息
let originArr = [
{phone: 13522147257, name: "张三"},
{phone: 15022147429, name: "张er"},
{phone: 15022147429, name: "张二"},
{phone: 18255726547, name: "李四"},
{phone: 13822475698, name: "alise"},
{phone: 13944125478, name: "alaen"},
{phone: 18222695475, name: "tom"},
{phone: 15033214759, name: 457},
{phone: 18755412698, name: 126},
]

将上述原始数据的格式改为：

{name:  '张三',  data:  {name:  '张三',  phone:  '15022147429'}}

//假设一原始数据为 originArr 很常见的用户信息
        let originArr = [

            {phone: 15022147429, name: "张二"},

            {phone: 18755412698, name: 126},
        ]
        //将用户名提取出来，做成如下数据结构 data 后跟原始数据就行
        // {name: '张三', data: {name: '张三', phone: '15022147429'}}

                    let wordFlag = word.test(it)

                    if (hanziFlag) {
                        if((!zh[i-1] || zh[i-1].localeCompare(it,'zh') <= 0) && (it.localeCompare(zh[i], 'zh') == -1)) {
                            curr.data.push(item2.data);
                        }

                    if (wordFlag) {

最终输出：
