Object Basics
๐จโ๐ผ Great! You can now create and work with objects.
๐ฆ When to use each notation:
Dot notation (
object.property):- When you know the exact property name
- Cleaner and more common
Bracket notation (
object["property"]):- When the property name is in a variable
- When property names have special characters or spaces
const key = 'name'
console.log(person[key]) // Dynamic property access
const weird = { 'full name': 'John Doe' }
console.log(weird['full name']) // Spaces in property name
Like arrays, objects declared with
const can still have their properties
modified. const only prevents reassigning the variable itself.
