When only consecutive duplicates need to disappear, <code>slices.Compact</code> handles the operation without a handwritten loop.</p> <p>The distinction is specific. <code>slices.Compact</code> collapses adjacent equal values; it doesn&rsquo;t search the entire slice for duplicates. It also modifies the slice&rsquo;s backing storage, so callers need to account for aliasing.</p> <h2 id="remove-adjacent-duplicates-with-slicescompact">Remove adjacent duplicates with slices.Compact</h2> <p>Pass a slice whose element type is comparable and assign the returned slice:</p>
