This is one of the most commonly used data-structures that we use in Javascript. It’s a dictionary.
It’s used as part of JSON - JavaScript Object Notation.
We can specific Javascript objects literally:
var Cars = {type:"Fiat", model:"500", color:"white"};
Javascript object values can be anything can be stored in a Javascript variable - such as a Javascript function i.e.:
var APPcommands ={
home : function(X) { console.log("Hello home "); }
};
It iterate through a Javascript object you can use:
for (var Car in Cars) {
console.log(Car, Cars[Car]);
}
