This article mainly explains "does JavaScript belong to language". The content of the explanation in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "does JavaScript belong to language"?

JavaScript belongs to the language. JavaScript is a lightweight, interpretive or just-in-time programming language with function priority. It is a dynamic scripting language based on prototype programming and multi-paradigm. It is often used to add a variety of dynamic functions to web pages and provide users with a more smooth and beautiful browsing effect.

JavaScript (JS for short) is a lightweight, interpretive or just-in-time programming language with function priority. Although it is known as a scripting language for developing Web pages, it is also used in many non-browser environments. JavaScript is based on prototype programming, multi-paradigm dynamic scripting language, and supports object-oriented, imperative, declarative, and functional programming paradigms.

JavaScript is a high-level scripting language belonging to the network, which has been widely used in Web application development. It is often used to add a variety of dynamic functions to web pages and provide users with a more smooth and beautiful browsing effect.

A complete JavaScript consists of the following three parts:

ECMAScript: provides the syntax and basic objects of the language

Document object Model (DOM): provides methods and interfaces for dealing with web content

Browser object Model (BOM): provides methods and interfaces for interacting with browsers.

JavaScript is commonly used to accomplish the following tasks

1. Embed dynamic text into HTML pages

2. Respond to browser events

3. Read and write HTML elements

4. Verify the data before it is submitted to the server

5. Detect the browser information of visitors

6. Control cookies, including creation and modification

The difference between JavaScript and Java

Many people see that Java and JavaScript have the word "Java" and think they are the same thing, even myself. In fact, the JAVA language and the JavaScript language are related, but they are not as closely related as you think. First of all, Java language is the product of SUN Microsystems company, while JavaScript is the product of Netscape company.

Secondly, they also have some differences in function: the application that Java runs on the client side is called Java Applet, which is embedded in the web page and has its own independent running window of Mini Program. Java Applet is precompiled, and an Applet file (.class) is opened and read with Notepad, which is simply incomprehensible. Java Applet is so powerful that it can access protocols such as http and ftp, and even grow viruses on computers (there is a precedent).

JavaScript, by contrast, is less capable. JavaScript is a "script" ("Script") that writes code directly into HTML documents and compiles and executes when browsers read them, so you can view HTML source files and JavaScript source code. JavaScript does not have a separate running window, and the browser's current window is its running window. I think the only thing they have in common is to use Java as the programming language.

Thank you for your reading, the above is the content of "does JavaScript belong to the language?" after the study of this article, I believe you have a deeper understanding of whether JavaScript belongs to the language, and the specific use needs to be verified in practice.
