Programming language

Programming language	Advantage	disadvantage
Python	Easy to learn and easy to link together various modules made in other languages.	Slower speed and some specific (unreproducible) bugs
C/C++	C/C++ can be embedded in any modern processor, almost all operating systems support C/C++, and the cross-platform is very good	It is difficult to learn, and has a large number of extremely complex functional interaction methods, which is easy to waste resources
Java	The most widely spoken language in the world	Java uses a lot of memory and takes a long time to start
C#	Fully integrated .Net library, providing excellent functionality and perfect library access	The cross-platform ability is too poor, and the employment environment in China is not very good, and the income is low
JavaScript	Low learning difficulty, and mastering the JavaScript language is equivalent to becoming a full-stack engineer who can develop web pages, backgrounds, and mobile terminals at the same time	Too much dependence on the browser, and the code runs on the user's computer, it is easy to be maliciously used by bad guys with ulterior motives
SQL	Fast development speed and good security	SQL development speed is traded at the expense of running speed, and portability is extremely poor
PHP	Large and active community, easy to get started quickly	It is slow and has a poor error handling mechanism, and needs to support a large number of functions of the old version
Objective-C	Has a wealth of tools and libraries	Have their own unique programming ideas, which are quite different from other programming languages
Swift	Swift is a growing percentage of code in iOS and OS X software	Versions change too fast, and different versions are too different
Kotlin	Excellent interoperability with Java	Inherited the inferior content of Java
