+A function can be used as an object property:
+```JavaScript
+const objectWithFunction = {
+ name: "Swapnil", // We can omit the " " in keys but for string values it is necessary
+ rollno: 76, // We assign any type to keys
+ getfull: function () { // Don't use arrow function here as arrow functions don't have this property
+ console.log(`${this.name} ${this.rollno}`);
+ }
+};
+
+console.log(objectWithFunction);
+// Output { name: 'Swapnil', rollno: 76, getfull: [Function: getfull] }
+
+objectWithFunction.getfull(); // Output Swapnil 76
+```
+
+Object property values can be changed using dot notation:
+```JavaScript
+const a = {
+ name: "Swapnil", // We can omit the " " in keys but for string values it is necessary
+ rollno: 76 // We assign any type to keys
+};
+
+a.name = "Swapnil Satish Shinde"; // This way we can change a particular property of object
+
+console.log(a.name); // This way you can get the value of particular element
+// Output Swapnil Satish Shinde
+```
+
+New properties can be added to an object after its creation:
+```JavaScript
+const canAddValue = { // This is normal object having 2 keys name and rollno
+ name: "Swapnil",
+ rollno: 76
+};
+
+// We can add the keys we want any time into the object by directly assigning value to it
+canAddValue.branch = "Computer";
+
+console.log(canAddValue);
+// Output { name: 'Swapnil', rollno: 76, branch: 'Computer' }
+```
