What are the programming languages ​​​​of Java, JavaScript, PHP, and Python used for development?

Java is often associated with "enterprise". Because it has some good language features and rich frameworks, it is the most popular in enterprise applications. You can always hear about things like J2EE, JSP, and Hibernate. discussion. At the same time, Java also has a place in the field of mobile phones. Before widespread intelligence, many mobile phones used supporting Java applications as a selling point. After the explosion of smart phones, the home of Java mobile phones became Android, which exists as the standard programming language of Android.

Summary:

Java: web pages, enterprise-level development, general application software, game backend.

javascript sounds related to java, but in fact there is no relationship at all, it is just a similar name. It is like the relationship between Leifeng Pagoda and Lei Feng, although there is only one word difference. The most widespread application of js is undoubtedly in the web front-end. To put it simply, what the website passes to you is a bunch of documents formatted with various tags, and js is responsible for manipulating these documents to achieve some client-side dynamic effects. The territory of js is not just that, now Node.js can also be used for server-side development.

Summary:

JavaScript is the scripting language of the browser. It is generally learned together with Html and CSS. It is mainly used for front-end development of websites and displays various cool pictures. You will often see the three words

php in the browser address bar, so it is not surprising that php is used to develop websites. It is also the king language of the web backend. Countless website backends run PHP code.

Summary:

PHP: Mainly a network front-end, used to generate web pages. You can also use PHP for the entire web server, such as many forum engines.

Because Python has a rich and powerful library, it is also called a glue language, which can easily connect various modules made in other languages ​​​​(especially C/C) together. A common application situation is to use Python to quickly generate a prototype of the program (sometimes even the final interface of the program), and then rewrite the parts with special requirements in a more suitable language, such as the graphics rendering module in 3D games. If the performance requirements are particularly high, it can be rewritten in C/C and then encapsulated into an extended class library that can be called by Python. Python is used for server development and Internet of Things development. Information security, big data processing, data visualization machine learning, Internet of Things development, APIs of major software, and desktop applications all require Python.

Summary:

Python: dynamic interpretation, high development efficiency, open source, flexible, and low entry barrier.
