As the sibling comment notes, VBScript isn't JScript, though both are executed by the Windows Script Host (wscript/cscript). JScript had already been deprecated in 2009 with IE 8.

VBScript is deprecated since 2023 and in the process of being removed: https://techcommunity.microsoft.com/blog/windows-itpro-blog/...

You also cannot run VBScript (nor JScript) from VB or VBA, other than invoking it as a separate process. VBA is not an "embedding of VBScript". VB/VBA are compiled to an intermediate representation called P-code, they aren't scripts in the sense of being executed from a textual representation like VBScript/JScript.
