Attributes & Properties
Get, set, and remove HTML attributes and DOM properties
javascript
// Set attribute
element.setAttribute('data-id', '123')
element.setAttribute('disabled', '')
// Get attribute
const id = element.getAttribute('data-id')
const href = link.getAttribute('href')
// Remove attribute
element.removeAttribute('disabled')
element.removeAttribute('data-id')
// Check attribute
if (element.hasAttribute('disabled')) {
// Element is disabled
}💡 Properties are faster than attributes for common values
📌 Data attributes are accessed via dataset property
⚠️ Attribute values are always strings
✅ Use properties for boolean values (checked, disabled)
