Javascript is simple but complex

Yesterday, I spent a day watching the Javascript video that Niu Yu talked about. It seems very simple. Maybe this video is intended for beginners.

For JavaScript, I personally think this is a very simple language, a dynamic language (a language that checks the data type during runtime. Programming in this type of language does not specify a type for the variable, but obtains the data type when values are attached. On the contrary, the static type language checks the type before compiling. Before writingCodeThe type must be specified for each declared variable ).

Javascript is simple, but complicated. For an inappropriate analogy, a computer layman asked you, "what do you mean by the software you wrote ?", You may say, "Oh, nothing, but it's 0 and 1 ." The layman will think, oh, it's that simple. But you know the complexity of these simple things. (Is this metaphor appropriate ?)

Javascript is also a very casual language. Whatever you say it is, what it is... :-)). However, this also reflects its easygoing nature.

There is nothing to say about the video of Niu Yu, but the later video of Jiang Hao is good. It will be a practical application. Now I have read this section, however, the instance in this video really needs to be done once. (Why? Because there is depth .)

After reading a video from Jiang Hao, I found that these cute JavaScript pages were so active. Although I knew it before, I didn't feel it myself.

Simple but not simple.
