JavaScript OBJECT STRUCTURE for Absolute Beginners
Whenever you learn a concept, break it down and look at the structure. Let's briefly talk about the structure of JavaScript object. JavaScript Object is a collection of properties. A property consists of a key value pair. Property key can also be called as property name.
To declare a JavaScript object and assign it values, use let, const or var keyword, type object name, use equal sign and open close curly braces. We have declared an object with the name person. And person has got it's properties. fullName and age are person's properties.
LET Keyword
Object has got let, var or const. let is a JavaScript reserved word. It can be var or const instead of let. There are many reserved words in JavaScript. In most cases const should be used to declare an object. In JavaScript you cannot use reserved words as variables, labels, or function names.
Object Name
Then we have object name. Person is the name of object in our video.
Object Properties
Inside object body we have properties. Each property has got key and it's value. In first property of person, fullName is the key. John Doe is it's value. In second property of person, age is the key. 20 is it's value.
When you look at the object like this and know it's structure, it will become easy for you to use it. In coming videos we will go deep into JavaScript Objects.
