Answer 1

I think you want something like this:

var print_string = function ( param, interval ) {
  var
    i = 0,
    len = param.length,
    
    result = document.getElementById( 'result' ),
    
    // function called for every characters
    next = function () {
      // get the current character
      var char = param.charAt(i);
      
      // do what you want with them
      result.innerHTML += char;
      
      // if not the end of the string
      if ( ++i < len ) {
        // continue after the interval
        setTimeout( next, interval );
      }
    }

  next();
}

print_string( 'hey there , whats up , hows the weather in Manhatten!', 50 );
