});

for (const key in obj) {
  console.log(String(key) + " -> " + obj[key]);

const getMethods = (obj: object): string[] => {
 const getOwnMethods = (obj: object) =>

     .map(([name]) => name)

上記をまとめた関数 †[edit]

function disp_obj(obj: object) {
   const getMethods = (obj: object): string[] => {
       const getOwnMethods = (obj: object) =>
       Object.entries(Object.getOwnPropertyDescriptors(obj))

       const _getMethods = (o: object, methods: string[]): string[] =>
       o === Object.prototype ? methods : _getMethods(Object.getPrototypeOf(o), methods.concat(getOwnMethods(o)))
       return _getMethods(obj, [])
   }

   console.log("+++++++++++++++++++++++++++++++++++");
   for (const key in obj) {
     console.log(String(key) + " -> " + obj[key]);
   }
   console.log("===================================");
