is there a method to get all propertys from an object code example

Example: javascript access property values list of objects

// Access all properties and values in a JS object:
let valuesArray = Object.entries(MyObject);
  
   for (let value of valuesArray) { 
       document.write(value + "<br>"); // value is the property,value pair
   } 
/* Result: propName,value
           propName,value
 		   ...

For clarity: */
let person = {
  name: "Piet",
  age: 42
};

Object.keys(person) // = ["name", "age"]
Object.values(person) // = ["Piet", 42]
Object.entries(person) // = [ ["name","Piet"], ["age",42] ]
