      console.log(result)
    }
    const newResult = result.map(obj => {
      const newObj = Object.keys(obj).reduce((acc, key) => {
        const newKey = key.replace(/ /g, '').toLowerCase();
        acc[newKey] = obj[key];
        console.log(newKey+'   newKey ')
        return acc;
      }, {});
      return newObj;

> re = /[\(\)\/\.\ ]+/g
/[\(\)\/\.\ ]+/g
> s="(10/04/2020)"
'(10/04/2020)'
> s.replace(re, "")
'10042020'

you can use regex to replace all those chracters.

let str = "experience(years)d.o.b (dd/mm/yyyy)";

function stripedStr(s){
  return s.replace(/[\(,\),\.,\/,\-,\_, ,]/g, "");
}

console.log(stripedStr(str));
