## console global variable

ScriptCraft provides a `console` global variable with the followng methods...

 * log()  
 * info() 
 * warn()
 * error()

The ScriptCraft console methods work like the [Web API implementation][webcons].

### Example 

    console.log('Hello %s', 'world');

Basic variable substitution is supported (ScriptCraft's implementation
of console uses the Bukkit Plugin [Logger][lgr] or Canary Plugin [Logman][cmlgr] under the hood and
uses [java.lang.String.format()][strfmt] for variable
substitution. All output will be sent to the server console (not
in-game).

### Using string substitutions

ScriptCraft uses Java's [String.format()][strfmt] so any string substitution identifiers supported by 
`java.lang.String.format()` are supported (e.g. %s , %d etc).

    for (var i=0; i<5; i++) {
      console.log("Hello, %s. You've called me %d times.", "Bob", i+1);
    }
