VBScript, or Visual Basic Scripting Edition, is a lightweight scripting language developed by Microsoft. It is primarily used for automating tasks in the Windows operating system and for creating interactive web pages. VBScript is easy to learn and is often used in conjunction with HTML to enhance web functionality. VBScript can be embedded in HTML pages and executed in web browsers that support it, although its use has declined with the rise of more modern languages like JavaScript. It is also commonly used in Windows environments for scripting tasks in applications like Microsoft Office and for automating system administration tasks.
