What is the difference between these two objects in Javascript?

Question

While doing console.log two arrays, I'm able to see them in this way:-

I don't understand the part that when both of them are of type object and have length 2, then why one shows up like (2) [{…}, {…}] and another like [] ?

Answer 1

In JavaScript

[ ]: This called array

Ex. var arr = [1,2,3];

{}: This called object

Ex. var obj= { "name": "hari","age":23};

From your example You can make array of objects

Ex. var arrobj = [ { "name": "hari","age":23},{ "name": "albert","age":50}];
