The main JavaScript to enable the submit interactions.

const DOM = {
  submitBtn: '.submit-button',
  submitPending: '.submit-button__pending',
  submitText: '.submit-button__text',
  submitLoaded: '.submit-button__loaded'
};
//find exact children of the button
const findChildren = elem => {
  
  return [
    elem.querySelector(DOM.submitPending),
    elem.querySelector(DOM.submitText),
    elem.querySelector(DOM.submitLoaded)
  ];
  
};
//find node parent function
const findParent = (elem, referenceElem) => {
  
  const className = referenceElem.slice(0, referenceElem.length);
  
  let ind = true;
  
  while (ind) {
  
    if(elem.classList.contains(className)) {
      break;
    } else {
      elem = elem.parentNode;
    }
    
  }
  
  return elem;
  
};
//onclick function for buttons - active state
document.querySelectorAll(DOM.submitBtn).forEach(elem => {
  
  elem.addEventListener('click', event => {
    
    let clickedElem = findParent(event.target, 'submit-button');
    
    const innerChildren = findChildren(clickedElem);
    
    //adding active class to the clicked elem
    if(! clickedElem.classList.contains('js-active')) {
      
      clickedElem.classList.add('js-active');
      
      innerChildren.forEach(elem => {

      });
