I would like to share a very flexible code based on this lecture.

I was playing around with the code explained in the video and I ended up with something like this. 

const div1 = document.getElementById('first');
const div2 = document.getElementById('second');
const div3 = document.getElementById('third');

function changeColor(options) {
    options.element.style.backgroundColor = options.color;
}

function applyBorder(options){
        options.element.style.border = options.border;

}
const actionWithOptions = {
    options: {element : div3,
    color: 'green',
  border: '5px solid black'},
    f: changeColor,
    f1: applyBorder
}

function addStyleToElement(actionWithOptions) {
    actionWithOptions.f(actionWithOptions.options);
      if(actionWithOptions.options.border && actionWithOptions.f1){
                actionWithOptions.f1(actionWithOptions.options);

        }
}

//method-1 : pass json const as options which changes color and apply border
addStyleToElement(actionWithOptions);

//method-2: pass json directly in the call
addStyleToElement({options:{element:div1, color:'red'},f:changeColor});
