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 a dynamic scripting language based on prototype programming, multi-paradigm, and supports object-oriented, imperative, and declarative ( such as functional programming) paradigm.

JavaScript is an interpreted language, that is to say, it does not need to be compiled in advance, but is interpreted and executed line by line by the interpreter at runtime. JavaScript is a weakly typed or dynamically typed language, which means that you do not need to declare the type of a variable in advance. The type of the variable is determined when you first assign a value to it, and can be changed later.

JavaScript was originally designed to add interactivity to HTML (an application under Standard Universal Markup Language) pages. However, 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, and declarative (such as functional programming) paradigms.

Overall, JavaScript is a powerful and flexible programming language that is widely used in web development and many other fields.
