Accessing the properties of an object
In JavaScript, you can use "." and "[]" to access the properties of an object.
1. Use "." to access object properties
Syntax:
objectName.propertyName
Where objectName is the object name and propertyName is the property name.
2. Use "[ ]" to access object properties
Syntax:
objectName[propertyName]
Where objectName is the object name and propertyName is the property name.
Methods to access objects
In JavaScript, you can only use "." to access methods of objects.
Syntax:
objectName.methodName()
Among them, objectName is the object name and methodName() is the function name.
