Adding code and textfield to Figma

I think that Figma should add a way to code so you can do more thing. Like javascript would be a good coding language that they could add, this could make it so you can do more stuff with what you making like: adding text to a textbox, having buttons change something about the same component, or changing which way a textbox is centered. I was just saying some random example, but with code it would allow you to make way cooler prototypes. Also it would be cool for Figma to add textfeilds because you could use that with the code to make a working search box for example.
