2. JS is easy to get started, but it's hard to go deep. There are many people who may do it, but few people do it well. One of my previous leaders also looked down on JS writing. He thought it was very simple, and it could be done with jQuery. He didn't consider performance at all. I read the code he wrote. It's a piece of shit, but he is my leader, and I can't spray him. This circle is impetuous. Influenced by various factors, few people devote themselves to cultivation. Some companies in order to complete the function and effect, not too professional people to develop, often a piece of code on the Internet is done. Do this job to get into the company, such as the network, Tencent, Taobao big companies are very focused on JS.

3. Recently, Xcode was used in the development of Mac OS X mountain lion. We found that there are two compilers in the compiler options: Apple llvm compiler 4.2 and llvm GCC 4.2

in recent years, it has been said that llvm is better than GCC, but I have no time to study the difference between the two. From this point of view, I put forward many questions to myself:
What are CC, C89, C99? What's the difference
What are GCC, G + +, CPP, GPP
is llvm different from GCC
what is the difference between Apple llvm compiler 4.2 and llvm GCC 4.2
is llvm GCC 4.2 llvm or GCC
next, let's make up the history class< After the birth of UNIX, many companies have developed their own UNIX systems and used their own special compilers. As a result, different commands are needed to compile c code on different UNIX systems. Therefore, the POSIX standard commands and utilities stipulates that CC should be used as a unified command interface for different compilers, and also specifies what parameters CC should provide
with the determination of subsequent ISO C standards, POSIX standard stipulates that C89 and C99 are used as the interfaces of ISO C respectively, while CC continues to be used as the interfaces of non-standard C. But in fact, most of the subsequent C language compilers have implemented the ISO C standard, so the POSIX standard stipulates that CC should be canceled< br />GCC, G++, CPP, GPP

4. Java is made by sun (now acquired by Oracle). You know. Net is made by Microsoft. Web started with B / S structure development, that is, browser access, not the kind of client (C / S structure). Java and. Net can do web development. However, it's totally different. SRC compilation and deployment are also different.

5. It was quite popular a long time ago, 14 years ago

6. For example, applets have launched their own JS
substitutes (typescript) for their own purposes, which other companies refuse. Then, each implementation wants to be integrated into the browser, but the key difference is "browser built-in support" and Google. All problems are solved. So we all see the problem. If we just talk about Microsoft like
coffeescript, some inherent defects of JS itself can't be avoided. We are all happy. No matter what is the difference between wasm and
ASM and Silverlight, they can't be organically combined with BOM Dom and dart.js

but like this, ASM, flash. If you like dart or clojurescript to build a runtime, it will lead to a huge amount of compiled JS code, so you have to follow the path of compiling to JS and then running! Therefore, when we do a set of bytecodes, parser often becomes a performance bottleneck.

7. To put it bluntly, Microsoft, Google and Mozilla all feel that JS is not good. For their own purposes, they have launched their own JS substitutes (typescript, dart, ASM. JS). Then the implementation of each family wants to integrate in the browser, other families are not willing to, so they have to go to the path of compiling to JS and then running

however, if we only add syntax sugar to JS like coffeescript, some inherent defects of JS itself can not be avoided. If dart or clojurescript are involved in a set of runtime, the amount of JS code compiled will be huge, and the parser will often become a performance bottleneck. So we all see the problem: "JavaScript specification has no bytecode"! So we have a set of bytecodes, all the problems are solved, and everyone is happy<

for instance, applet, flash and Silverlight, wasm are obviously not the same thing, and they can not be organically combined with BOM dom

in addition, I oppose @ Yu Jianrong's answer. No matter what other differences exist between wasm and ASM. JS, the key difference is "browser built-in support".
