Isn't javascript a java language?

In many people’s perception, Java and JavaScript are the same programming language, or they are variants or extensions of the Java language. However, in fact, Java and JavaScript are two completely different programming languages, although they have some similarities.

Java is a cross-platform object-oriented programming language developed by Sun Microsystems (now Oracle Corporation). The Java language is characterized by portability, security, and reliability, and is widely used to develop various types of applications, including desktop applications, web applications, and mobile applications. In Java, developers need to write Java code, then compile it into a bytecode file, and finally run it in the Java Virtual Machine.

JavaScript is a scripting language commonly used in web development. It was first launched by Netscape and was initially named "LiveScript" and later renamed "JavaScript". The syntax of JavaScript is similar to C language and Java language, and supports various programming paradigms. It is mainly used to add interactivity and dynamic effects to Web pages, such as responding to user input, modifying document content, dynamically loading resources, etc. In JavaScript, developers only need to write JavaScript code in a Web page, which can then be run directly in the browser.

The relationship between the two is that JavaScript was originally designed to add some simple dynamic effects to Web pages, but due to its ease of use and flexibility, it has become a popular programming language. Although JavaScript contains "Java" in its name, it actually has little to do with Java.

Some developers may confuse Java and JavaScript, perhaps because their names are very similar, or perhaps at some point in the past, JavaScript was promoted as "Java script" by some marketing teams. This misconception says a lot about the popularity of programming languages and the difficulty developers have in learning and understanding new technologies.

Just like Spanish and Dutch, whose names contain the word "language" and have similar pronunciations, but are two completely different languages, Java and JavaScript are also two completely different languages. programming language. For those who are not very familiar with programming or IT fields, understanding the difference may take some time and effort, but correctly identifying the two languages is crucial to handling programs correctly and ensuring network security.
