JavaScript Types of Value

As in Mathematics, you need 2 type of Values i.e. Constant and Variables. to do Operations

Same as in Javascript, you have to use 2 type of Values :

1. Constant or Fixed Number these are called as Literals
2. Variables.

Javascript Literals

There can be 2 Types of Values that can be termed as Literals.

1. Numbers :
2. Any Numeric Number can be considered as Literals.
3. Example : 10, 20.5, 500 , 999.79
4. Strings :
5. Strings are Same as Text.
6. Example : "Javascript" , "World of Programming".

To Write a String, you have to write it within double or single quotes.

Javascript Variables

Same as in Mathematics, Variables are used here to Store values.

In Javascript to Declare a Variable, you have to use a Keyword  var .To Store Values in Variables  equal sign (=)  is used.

For Example :

var x;
x=10;

var y;
y=20.5;

var z;
z=999.79

Here,

10 is stored in x, 20.5 is stored in y and 999.79 is stored in z.

In Variables, you can store All Literals(numbers and string)

For Example :

var x;
x=10;

var y;
y = "Hello World"

Here, the Literal  "Hello World"  is stored in variable y.

In Later Section, We will got deep into Variables.
