Getting the value of an object's property

+

Let's take one of the objects we looked at earlier..

+
let laptop = {
+    brand: "Lenovo",
+    screenSize: 13,
+    isTouchscreen: true
+};
+
+

Try to console.log(laptop). The output might depend on your environment!

+
+

To find out the value of an object's property, you can use the dot notation..

+
console.log(laptop.brand);
+

You can also use the bracket notation (although this is rarely used, it's good to know):

+
console.log(laptop['brand']);
+

Setting the value of a property

+

Similar to reading, if we want to set a property:

+
laptop.brand = "Apple";
+

It's strongly recommended you always use the same type when re-assigning an object's property (if it was a string before, keep it a string - and so on).

+
let laptop = {
+    brand: "Lenovo",
+    screenSize: 13,
+    isTouchscreen: true
+};
+
+// DON'T DO THIS
+laptop.screenSize = "15 inch";
+
+// OK TO DO
+laptop.screenSize = 15;
+
+
+ +
+ + + + +
