Now what do you know about visualforce : it’s a markup language used in salesforce.com

basically everythings works on MVC model view and control

1. in force.com or sfdc we have Model in which We use sObject (Salesforce object) like account ,case , lead etc above menus.

2. For View (Front end) we have Layout(Page, Field etc) AND we use Visualforce language for this purpose,
Although in salesforce a lot can be done by declaration, mouse click and drag drop.
3. Controller is the main part where a programmer write the logic and business code.
it is of 3 types Standard controller, Custom controller,controller extension

you can create your first visualforce like this

after that you can choose new or developer console.

in developer console click New visualforce page
you will see
c

here apex is namespace and page is tag (namespace is way to group different things)

it's first code

If we want to use expression then
synatx will be like{!----}

if we will access global variable then we use $ 
e.g {! $user.firstname}
Expression {!--} can conatin 3 things

static expression like {!2*2}
global variable {! $user.firstname}

properties of sObject made available through controller
e.g. today -->  {!Today()}
tomorrow  --> {!Day(Today()+1)}
Square root --> {!SQRT(49)}
Max ---> {Max(1,8,2,6)}
find---> {!Contains('Saifi','fi')}
  

Congratulations

This is your new Page Welcome {!$user.firstname} {!$user.lastname},
you know today is{! YEAR(TODAY())}

hi ok no

{!max(1,2,3,4,5,6)}

{! sqrt(111)} {!contains(‘saleforce.com’,’com’)}
