The difference between JavaScript and VBScript:

1. Differences in annotations

There are two kinds of Javascript comments, which are single-line comments / / and multi-line comments / * /

Vbscript comments are annotated with single quotation marks'

2. Differences in declaring variables

There are three ways to declare JavaScript variables, using the var, let, and const keywords.

Vbscript is defined as Dim, but it must be declared before it is assigned

Such as:

Dim nnumbernumber=12

3. Syntactic differences

The JavaScript syntax is similar to the C programming language and is a case-sensitive language.

The VBScript syntax is similar to visual basic in that it is based on Visual Basic and follows the basic syntax of visualization for application development. It is a case-insensitive language

4. Browser support

JavaScript is the default scripting language for most Web browsers and supports almost all Web browsers because it supports cross-platform. It can read and modify HTML elements from IE browsers and automate ActiveX components in browsers.

VBScript is not the default scripting language for browsers because it only supports Internet Explorer or Microsoft Edge browsers. We need to specify it as a scripting language. It can read and modify HTML elements from IE browsers and automate ActiveX components in IE browsers.

5. Functional support

JavaScript is an object-oriented scripting language, it is not perfect object-oriented, does not support the concept of inheritance. It supports powerful object usage and class declarations to create objects later, and does not support programs.

VBScript is also a partially object-oriented scripting language. It does not support inheritance concepts, the use of objects, object creation, and user-defined classes. It supports reusable functions and subroutines.
