I think you want something like this:

const capitalize = (s) => {
  if (typeof s !== 'string') return ''
  return s.charAt(0).toUpperCase() + s.slice(1)
}

let content="power_managment 0vol 0vol 0vol 0vol0vol 0vol test 123vol";
let content2 = content.split(" ")[0].split("_");
console.log(content2[0] + "" + capitalize(content2[1]))
