I started working on learning Android Development from Udacity.
It is a free course and is being tought by people working at Google.

If anyone is interested you can go to this link :

Android Basics

The first few lessons explain about Views in Android

A View is an individual element that is used to represent a type of content on the screen, multiple views are combined to form the layout of the app

There are different kinds of views :
TextView : Represents text
ImageView : Represents images
Button : Represents buttons

There also exercises that help us understand how different views are used to build a layout

XML tags are used to build these views
Example : To show some text on a screen we use the TextView tag
We can add attributes to the tag to further add more details , such as textColor and background

I feel this would be a really good course for someone intrested in getting started with Android Development

Variables in JavaScript

Variables are used to store data on a computer.

There are different type of data that you can store in a variable, the following are different types of data types:

string
number
boolean
object
null
undefined
symbol
BigInt
function

Variables are accessed with a label, not with the data itself.

Let me explain the above point, firstly to create a variable you need to use the "var" keyword followed by a name for the variable and then assigning a value to it from any of the above data types.

Ex: var count = 20;

Here "count" is called the label. When we need to use the variable later we use its label to get the value stored in it.

Here we have stored a number 20 in the variable with a label count.

Hope this has helped you understand how to use variables.
