RMMV Use skill without ending turn using JavaScript

[Bluub]

I want to set a skill for a character that changes stats but I don't want the skill to consume a turn. While I know that Yanfly's Instant Cast Plugin literally does this, I was wondering if it was possible to do using Javascript

P.S. I am terrible at Javascript

I am aware of Yanfly’s instant cast, I want to know if there is a way to do it using Javascript solely.
