我想找到++或 - 或//或**在字符串中登录可以有人帮助我吗？

var str = document.getElementById('screen').innerHTML;
var res = str.substring(0, str.length);
var patt1 = ++,--,//,**;
var result = str.match(patt1);  
if (result)
{
    alert("you cant do this :l");
    document.getElementById('screen').innerHTML='';
}

我有一个像这样有 n 个成员的对象：

 {
  open: '122.31000000',
  high: '137.50000000',
  low: '119.50000000',
  close: '135.92000000',
  volume: '1436796.12449000',
  closeTime: 1585007999999,
} 
{
  open: '132.63000000',
  high: '137.13000000',
  low: '121.10000000',
  close: '122.32000000',
  volume: '1055699.86532000',
  closeTime: 1584921599999,
}

我想在不使用任何 for 循环的情况下像这样转换这个对象，我该怎么做？

{  
  o: '122.31000000',
  h: '137.50000000',
  l: '119.50000000',
  c: '135.92000000',
  v: '1436796.12449000',
  d: 1585007999999
},
{
  o: '132.63000000',
  h: '137.13000000',
  l: '121.10000000',
  c: '122.32000000',
  v: '1055699.86532000'
  d: '1584921599999'
}
