| Like every other programmer, I wanted to know, what **Monads** are. But every time you search for Monads on the internet, you get flooded with category theory papers. And other resources don’t seem to make much sense either. | ||
| 和其他程序员一样，我也想知道 **Monads** 是什么。但是每次在网上搜索 Monads，都只会找到大量的 Monads 理论范畴文章，而其它资源似乎也没有参考意义。 |

| To learn what Monads are, I did it the hard way. I started learning Haskell. Only to realize, after few months, that people make too much of a fuss of Monads. If you’re a JavaScript developer, you’re most definitely using them daily. You’re just not aware of it. | ||
| 为了学会什么是 Monads，我花费了大量时间精力。我开始学习 Haskell，几个月后才发现，人们对 Monads 太小题大做了。如果你是一名 JavaScript 开发人员，那么你肯定每天都在使用它们，你只是没有意识到而已。 |
