onMouseEnter:
This event is triggered when the mouse cursor enters the target element. It is commonly used to trigger actions when the user hovers over an element.

// Example: Change background color on hover
element.onmouseenter = function() {
  element.style.backgroundColor = 'yellow';
};

onMouseOver:
This event is triggered when the mouse cursor moves over the target element or any of its child elements. It can be used to track mouse movement within an element and trigger actions accordingly.

// Example: Log mouse position over an element
element.onmouseover = function(event) {
  console.log(`Mouse position: ${event.clientX}, ${event.clientY}`);
};

onMouseLeave:
This event is triggered when the mouse cursor leaves the target element. It is useful for triggering actions when the user stops hovering over an element.

// Example: Reset background color when mouse leaves
element.onmouseleave = function() {
  element.style.backgroundColor = '';
};
