Auto Printer automatic Typewriter effect

Some time ago I saw the effect of a typewriter, so, on impulse, I also wrote a typewriter effect.

Relatively simple, but still need to optimize the place, because they feel that the effect is not flashy, and so on which day to come up with good ideas. Again to update ...

var timer;
var str = "I like to go." n every place that arrives, belongs to yesterday. Even if the mountain again green, the water again show, the wind again gentle. Too deep linger becomes a kind of fetters, stumbling not only have both feet, still have the future. n How can you not like to start? have not seen the towering mountains, it is really a pity, see the mountains of towering not seen the vastness of the sea still regret, see the vast expanse of the sea has not seen the vast expanse of the desert, still regret, see the vast expanse of the desert has not seen the mysterious forest, or regret. There are endless scenery in the world, I have not the old mood. n I naturally know that the mountains have bumpy, the sea has waves, the desert has sand, the forest has the beast. Even so, I still like it. n Break the Peace of life is another scene, a kind of young scenery. I'm glad I'm not old enough. Even if it is really old, what is not a word called Hale? n So, I also want to learn from the mountains deep, I also want to learn from the sea of courage, I also want to learn from the desert calm, I also want to learn from the forest alert. I want to learn to taste a colorful life. How far can n people go? This is not to ask the two feet but to ask ambition, how high can people climb? This is not about asking your hands but asking for the will. So, I want to use the blood of youth to their own tree up a lofty goal. Not only to strive for a glorious, but also to pursue a realm. The goal is achieved, is glorious, the goal can not achieve, life will be because of this journey to enrich and enrich, in my opinion, this is not a lifetime. n Yes, I like to go, and I hope you like it.
