is.js

is.js is a micro javascript library that helps you with conditions.

Examples:

// Object functions:
var str = 'my string';
str.isString(); // return true
str.isEmpty(); // return false
str.isArray(); // return false

// new in v1.2
str.isBlank();   // return false
''.isBlank();    // return true
'   '.isBlank(); // return true

// new in v1.3
'this@email.com'.isEmail(); // return true
'5156300575820365'.isCC() // return true
'5156300575820365'.isCC( 'Visa' ) // return false

// also is.js have some core functions:
is.windows();
is.chrome();
is.mobile();
is.online();

if(str.isString()){
  // do stuffs here
}
if(is.desktop()){
  // do stuffs here
}

How to use:

First of all you need to add is.js to your website, before your main javascript:

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<title>My homepage</title>
</head>
<body>
	
	<script src="is.min.js"></script> <!-- insert is.js -->
	<script src="main.js"></script>   <!-- your main javascript -->
</body>
</html>

After that you have already finished with the installation. Inside your main script you can already start using is.js!
