Coding Snippets Used In Almost All Languages

Here i had tried to publish some logic's that helps us in understanding the vast & robust world of coding. As we go ahead with our programming approaches we tend to forget our basics so this post will help us in reviewing the basics of the coding standards and provides us some code snippets as a help.

//code snippet as an example
var a=1;

a=a-b; // i.e. a=6
document.write("a="+a +"
b="+b) ;
