• Mouse Events: click, dblclick, mouseover, mouseout, mousedown, mouseup
• Keyboard Events: keydown, keyup, keypress
• Form Events: submit, change, input, focus, blur
• Touch Events: touchstart, touchend, touchmove (для мобильных устройств)
• Window Events: load, resize, scroll
• Custom Events: создаваемые через new CustomEvent()

Пример обработки click и input:

button.addEventListener('click', () => console.log('Clicked!'));
input.addEventListener('input', (e) => console.log(e.target.value));
