What are JavaScript Objects?

What are objects?

Objects are use in JavaScript. Objects store values. these can store any type of data as values. The store value can be any value such as a string, number, an array, or even a function.

How do we use objects?

Objects use the ‘keys’ to refer to the stored values. Objects are unordered collection using the key-value pairs. for example.

let person = {

name: ‘John Doe’,

age: 30,

human: true


name is the key, and the string ‘John Doe’ is the value. this is called the key-value pair.

How do we access the values in objects?

To access the access the value we use the bracket notation or the dot notation. for example.

person[‘name’] => ‘John Doe’

person.age => 30

What is Rails?

Rails is framework that actually comes from Ruby which is why it’s called Ruby on Rails. Ruby on Rails is used for back-end application. You could definitely create a web application using only Rails and following the MVC pattern. MVC basically stands for model-view-controller.
