10. Systems Register js fundamentals

function systemRegister(args) {
  const sysRegister = {};
  args.forEach((element) => {
    const [systemName, componentName, subcomponentName] = element.split(' | ');


    if (!Object.prototype.hasOwnProperty.call(sysRegister, systemName)) {

      sysRegister[systemName][componentName] = [];
    }

    sysRegister[systemName][componentName].push(subcomponentName);
  });

  const sysRegisterSorted = Object.keys(sysRegister).sort((a, b) => Object.keys(sysRegister[b]).length - Object.keys(sysRegister[a]).length || a.localeCompare(b));

  sysRegisterSorted.forEach((key) => {
    console.log(key);
    const subKeysSort = Object.keys(sysRegister[key]).sort((a, b) => Object.keys(sysRegister[key][b]).length - Object.keys(sysRegister[key][a]).length);
    subKeysSort.forEach((element) => {
