Chapter 5: JavaScript Objects

Object Basics

Create objects:

let object_name = {
    property_1_name: property1_value,
    property_2_name: property2_value,
}

To access a single property, using . (dot) operator

Check code in object-101.js

Using Objects with Functions

Parse objects into function just like normal number, it allow us to parse multiple values into function as a single value. Or get multiple values as single value from a function

Exmple check object-function.js

Object References

When a object is parsed as argument into function, it's parsed as reference (not as a copy). Changes done by function on object affect original object

But when a new value to the argument (in function), it break the binding (pass as reference) within function. But does not affect the original object

Example check object-references.js
