//In Chrome & Firefox (+31) you can add CSS in console.log messages:
console.log('%c Oh my heavens! ', 'background: #222; color: #bada55');
console.log('%c%s', 'color: red; background: yellow; font-size: 24px;', 'WARNING!');

//normal output:
console.log ( 'String:', {a: 'object, or any kind of type here'}, ['and you can use it like args'] );

//formatted output:
- %s — string
- %d or %i — number (digit, integer) 
- %f — floating-point number
- %o — like dom element
- %O — like js object
- %c — styled by css
