Types of Initializing Variable

var roll;
roll = 101; var roll = 101; roll = 101;

var name;
name = “devopsschool.com”; var name = “devopsschool.com”; name = “devopsschool.com”;

price = 125.36;
Initializing Variable var price = 125.36; price = 125.36;

Whatever happens, is optional so only you roll = 101; can also write. Var is not necessary but if you use this is a good practice.

Rules of Initializing Variable

• Strings are written inside double or single quotes.
• Numbers are written without quotes.
• If you put a number in quotes, it will be treated as a text string

Initializing Variable

var ans = true;
var result = false;

Initializing Variable example

var x = 10, y = 20, c = 30;
var fname = “DevOps”, lname = “School”;
var name = “DevOpsSchool”, roll = 101;

var name = “DevOpsSchool”,
roll = 101,
address = “Steel City”;
