Closure event listener

closureEventListener.js

/**
 * Imagine we had an event listener that would control toggling a visibility class of an element
**/
 

const toggleVisibleClass = event => {
    console.log(event.target.value + 'changed');
    someTarget.classList.toggle('is-visible');
}

checkbox.addEventListener('change', toggleVisible, false);

/**
 * We could pass the dom node in that we want to change, 
 * this enables us to keep using this function on different checkboxes 
 **/

const toggleVisibleClass = domNode => event => {
    domNode.classList.toggle('is-visible');
}

const myForm = document.querySelector('.the-form');

checkbox.addEventListener('change', toggleVisibleClass(myForm), false);
