# OBUFFER

OBUFFER stands for Output Buffer.

* It is a keyword.
* It is used to store values in output buffer.
* To display content of OBUFFER, use ***'console'*** attribute.

```javascript
{
   name : Main
   
   @ use += to add content to OBUFFER
   OBUFFER += 27062003
   OBUFFER += "\tSaksham Joshi"
   
   @ to display content on terminal
   console : ( OBUFFER )

   @ remember you **cannot** print the OBUFFER using print or println
   @ println( OBUFFER )
   @ because OBUFFER is managed by interpreter itself 
}
```

<mark style="color:yellow;">**OBUFFER can speed up your code's speed by 100 times if you use it smartly.**</mark>\
\
Look at this code for instance:

```javascript
{
   name : Main
   
   for : {
       range : ( Int i = 0 , 10000 )
       console : ( i , '\n')
    }
    
    console : ("\n Time taken = " , getExecTime())
}
```

And if I want to optimize this code using 'OBUFFER', then

```javascript
{
   name : Main
   
   for : {
       range : ( Int i = 0 , 10000 )
       OBUFFER += i
       OBUFFER += '\n'
    }
    
    console : ( OBUFFER, "\n Time taken = " , getExecTime())
}
```

Run these both code and you will understand how OBUFFER can be used to achieve greater optimization levels.
