📚 Topic Summary
ARIA (Accessible Rich Internet Applications) attributes enhance web accessibility by providing semantic information to assistive technologies, like screen readers. While JavaScript enables dynamic web content, using ARIA isn't always necessary. Employ ARIA judiciously, primarily when standard HTML elements lack the semantics to convey the behavior and relationships of custom UI components. Overusing ARIA can create a confusing or conflicting experience for users. The best practice is to use semantic HTML whenever possible and augment it with ARIA only when necessary.
