Answer 1

Or something like that:

function snake2CamelCase(string) {
  return string
    .replace(
      /_(\w)/g,
      ($, $1) => $1.toUpperCase()
    )
  ;
}

function snake2PascalCase(string) {
  let s = snake2CamelCase(string);
  
  return `${s.charAt(0).toUpperCase()}${s.substr(1)}`; 
}


[
  'something_went_wrong',
  'thisIs_my_snakecase'
]
  .map(s => ({[s]: snake2PascalCase(s)}))
  .forEach((s, i) => console.log(i, s))
;
