Curly brackets for function blocks on one line

I am getting back to writing javascript after not using the language for several years.

It used to be thought that using built-in functions such as

doSomething(function() console.log('its done'));

      

        
        
        
      

    

will work in all important browsers. Now it seems that chrome is having problems with this:

Uncaught SyntaxError: Unexpected identifier

      

        
        
        
      

    

But not with this:

doSomething(function() {console.log('its done')});

      

        
        
        
      

    

What is the reason for the severity of chrome? Where can I read about this? Does it make sense and finally how can I disable it? I prefer the no-curly brace option for simple liners.
