This quick JavaScript review video is regarding Learn JavaScript on Codecademy, Objects Section, Review Lesson. This JavaScript Object Review goes over the different JavaScript object fundamentals we have been learning in the previous lessons. We go over all the object basics such as the fact that objects are stored in collections of key-value pairs. We are taught that when a property is a function, we call that a JavaScript method! Our key-value pairs are separated by commas! We learned that we are able to access, edit, or even add properties to an object by using bracket notation and dot notation. We are able to add methods to object literals by using key-value syntax and giving the value an anonymous function or by using new ES6 method syntax. By chaining operators we are able to navigate complex objects that are nested. Never forget that JavaScript objects are mutable. Pass by reference taught us that when changes are made to an object passed in as arguments, those changes are forever permanent. We last learned about the for-in loop which allows us to iterate through our objects! Make sure to practice javascript objects to really learn how to master them!
