what does javascript mean

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

JavaScript is an interpreted language, which is different from C++ and C languages ​​(compile first and then execute). It is interpreted for each line during the running of the program. JavaScript is not only an object-based scripting language, it can create objects and use existing objects directly.

JavaScript is an event-driven scripting language, such as when a user visits a web page, the mouse clicks, moves, etc. JavaScript can directly respond to these times, and does not need to respond to user behavior through a web server.

javascript features:

1. Simplicity

JavaScript is a weakly typed variable type, and there are no strict requirements for data types. Its design is simple and compact.

2. Cross-platform

Javascript does not need to rely on the operating system, as long as the browser supports it, it can be directly used after compilation to any scripting language that supports the browser, and javascript has been supported by almost all browsers.

What is JavaScript? What is the use?

JavaScript is an object-based and event-driven scripting language with security features.

The Javascript scripting language, like other languages, has its own basic data types, expressions and arithmetic operators and the basic program framework of the program. Javascript provides four basic data types and two special data types for processing data and text. Variables provide a place to store information, and expressions can complete more complex information processing.

Differences between JavaScript and Java.

Java code must be compiled to execute, while JavaScript does not need to be compiled, it only needs to be interpreted and executed by the browser.

Although both Java and JavaScript can be executed on the server and the client, Java mostly runs on the server, while JavaScript mostly runs on the client.

JavaScript uses loose data types, while Java uses strict data types.
