Introduction to JS
Introduction Of Javascript
We are having mainly two types of data types in Javascript which are as follows :-
Mainly we declare our data types just by using var , although we are having different declaration also by which we can declare our data type, but we will be reading about them later
Syntax
var a = 50;
var b = "Manish is my name";
So like this we can declare our variables

| Data Type | Description |

| String | declares the sequence characters inside (" "). |
