You should declare the named handler function first, like «function myHandler () { /* ... */ }» and then attach it inside the loop by name - «Array.from(document.getElementsByClassName('saveBtn')).forEach(function (elm) { elm.addEventListener('click', myHandler) })». Avoid using anonymous functions this way 'cause for each element in loop you force the browser engine to create new function instance (the same anonymous function) from scratch again and again. Moreover, anonymous functions cannot be detached from listeners

Required Parameters for Functions in JavaScript

 const isRequired = () => { throw new Error('param is required'); };

const hello = (name = isRequired()) => { console.log(`hello ${name}`) };

// These will throw errors
hello();
hello(undefined);

// These will not
hello(null);
hello('David');
The idea here is that it uses default parameters, like how the b parameter here has a default if you don’t send it anything:
function multiply(a, b = 1) {
  return a * b;
}
