The difference between javascript and vbscript

1. Different developers

JavaScript is a Netscape company A lightweight, interpreted or just-in-time compiled scripting language developed 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.

VBScript is a general-purpose scripting language developed by Microsoft, also known as active scripting language. It uses a common object model to access environment variables and file system objects for read, write, update, and delete operations. VBScript is only supported by the browser Internet Explorer and is primarily used in Microsoft environments and visual base language products.
