JavaScript (i)--Learn from comparisons

JavaScript is not the first day of contact, in the previous hit the beef Brisket press release system used, and later study of the Beida Jade Bird's ASP. Used things, do a summary, this section, I only write the introduction of JavaScript, then there will be other articles introduced.

(i) JavaScript

A scripting language, which is a language of interpretation (understanding the differences between interpreted and compiled languages), simply explaining that the interpretation language is executed by interpreting the scripting language, which is to be inserted into other languages (e.g. HTML), and that the compiled language is compiled into a computer language by the compiler and can run independently.

See Mind map:

Here's a summary of the basics of JavaScript in the video, which is, of course, the most basic thing. It is important to know that JavaScript is completely object-oriented, so it has object-oriented things, JavaScript is event-driven, the saying goes that the event triggers the mechanism. Simply understand that when you call JavaScript, you should all have written onclick= "javascript events", similar statements.

(b) Compare the difference between VB and JavaScript

When I draw a summary of JavaScript, I think it looks like a picture I drew before:

The following picture is 2 years ago I summed up the time of VB painting, very early, I have nothing to modify, really feel like two pictures.

Let's just say: we have a lot of things we have learned before, such as data types, three structures, controls (components). These very basic things, put in a different place, but there are a lot of things are the same, so that we can learn more efficiently.

(iii) Summary

In the video there is a column ah, the regular expression of God horse. Later also will be mentioned in the blog, because I think put in an article will appear very abrupt, the Chinese teacher said: The big goal into small goals, written series of articles, the individual feel that said very reasonable, so do.

This blog really feels that there is no technology to speak of. This is a stage of cognition, and when we look back, we may find that we are changing slowly!
