Ethereum JS browser development video

1. A: the fact of the future earth mineral pool of FEM can be found in the Ethereum browser.

2. Ethereum browser's website is etherscan.io, you can query Ethereum related details. At present, the exchanges that can trade Ethereum mainly include: coin an, fire coin, bitnet, etc.

3. JSP is compiled and executed by the server. JS is interpreted and executed by page browser, and the timing of execution is different
1 Java is a strong type programming language at the same level as C / C + +. It is purely object-oriented and much more complex than JSP and JavaScript. Generally, if you learn java well, you can easily switch to the other two languages

2 JSP is the acronym of java server page. As the name suggests, JSP is the server page of Java, and its dynamic syntax part is completely Java specification. JSP is the same server-side language as ASP and PHP, which is mainly used to make the technology of website background (but it is generally not used now, and template engine technology such as velocity has been used since 2014)<

3 java script means java script from its name. It is a script language that runs in the browser. Because most of its syntax specifications are derived from Java syntax specifications, it is named java script (in fact, it has nothing to do with Java. It is designed and implemented by Brendan EICH of Netscape company for the first time on Netscape Navigator browser. Because Netscape works with sun, Netscape management wants it to look like Java, so it's called JavaScript. JavaScript is an object-based weakly typed scripting language, which is mainly used to make the foreground technology of web pages. It is also the core of the popular Ajax technology.
generally speaking, Java is a programming language for the background, JSP and JavaScript are used for the foreground page programming

4. This is very important and will be of great help to the future development
to connect your software with your hardware, you need to set up the required hardware and software settings first
Terminal Design and analysis. Because your software must be used separately. Think about it better
it's very important to see what kind of language your programmers use, and the later testing.

5. Now Android browser supports video very well. You can use the video tag to load MP4 format video directly. It can be used for personal test.

6.

Developer tools don't have this function. They are mainly used for web debugging. You can use browser extensions to meet your requirements

Dynamic web:HTML + CSS + Javascript + PHP + database combination In request -- & gt; Server lookup data -- & gt; Back)
development history: CGI (Common Gateway Interface): early technology, excessive consumption of system resources, and little use at present
ASP: Microsoft's dynamic server technology (less)
jsp: Java Server Technology (high security)
PHP: Hypertext preprocessor (widely used)

9. It is recommended that you use UC browser. UC uses its own U3 kernel, which can open web pages quickly and give you the ultimate browsing experience,
