function for javascript dom style property

Question

I want to make a function like this.

const displayTextContent = (dom, content) => {
  dom.textContent = content;
};

for the dom style property

but when I made a function for this, javascript didn't light up the second parameter in the parentheses ignored the parameter after the style

const elementsStyleFn =function (dom, type,s) {
  dom.style.type=s
};

and pass parameters like the code below

elementsStyleFn(body,backgroundColor,'red')

in the consol say (backgroundColor) undefine

I hope my question Is clear enough.
