nl_tokens: * @method fill ( <arg1 > <arg2 > ... ) @returns Function @short Returns a new version of the function which when called will have some of its arguments pre - emptively filled in also known as currying . @extra Arguments passed to a filled function are generally appended to the curried arguments . However if %undefined% is passed as any of the arguments to %fill% it will be replaced when the filled function is executed . This allows currying of arguments even when they occur toward the end of an argument list ( the example demonstrates this much more clearly ) . @example
pl_tokens: function ( ) { var fn = this , curried = multiArgs ( arguments ) ; return function ( ) { var args = multiArgs ( arguments ) ; curried . forEach ( function ( arg , index ) { if ( arg != null || index >= args . length ) args . splice ( index , 0 , arg ) ; } ) ; return fn . <mask> ( this , args ) ; } }
