Objects are, according to Merriam-Webster is something material that may be perceived by the senses. While Arrays, are, according to Merriam-Webster is a number of mathematical elements arranged in rows and columns.
In JavaScript, Objects are used to model real-world objects, giving them properties and behavior just like their real-world counterparts while Arrays, according to w3schools.com are used to store multiple values in a single variable.
This is an object :
let dog {
name: "LeBrown",
numLegs: 4
};
While this is an array:
var cars = ["Volkswagen", "Volvo", "Merc"];
The difference of both are:
1.) Arrays are just objects but with some extra methods.
2.) There is nothing an object can do that an array can’t.
As a general rule of thumb, if you need to store a collection of properties with varying types, use an object. Otherwise, use an array.
