拼接字符串

实现输入：value = 10；输出：'11-88-1010'

let list = [{
    value:1,
    text:'11',
    children:[{
        value:2,
        text:'22',
        children:[{
            value:7,
            text:'77'
        },{
            value:3,
            text:'33'
        }]
    },{
        value:8,
        text:'88',
        children:[{
            value:9,
            text:'99'
        },{
            value:10,
            text:'1010'
        }]
    },{
        value:11,
        text:'1111',
    }]
},{
    value:4,
    text:'44',
    children:[{
        value:5,
        text:'55',
    }]
},{
    value:6,
    text:'66'
}]

function getTxt(arr = list,value = 10){
    let txtArr = [];
