Answer 2

const res = demo([
  [10.09, 10.11],
  [10.13, 10.22],
  [10.14, 10.15]
])

console.log(res) // => [["10-09", "10-11"], ["10-13", "10-22"], ["10-14", "10-15"]]

function demo (list) {
  list.forEach(up => up.forEach((item, index) => {
    up[index] = String(item).replace(/\./g, '-')
  }))
  return list
}

Answer 3

var dataarr=[
            [10.09,10.11],
            [10.13,10.22],
            [10.14, 10.15],
        ];   

dataarr.forEach(function(value,index,arr){
    value = value.toString();
    value = value.replace(/\./g, '-');
    value = value.split(",");
    arr[index]=value;
});

Answer 4

代码挑战赛么？

const newData = dataarr.map(
  arr => arr.map(
    num => ('' + num).replace('.', '-')
  )
)
