Sometimes I just want to know what the syntax is... sometimes documentation can be VERY dense, but someone on SO has posed a question or answer that can show me how the syntax works for that one specific thing I'm looking for. Particularly useful for frameworks like Svelte or React where I'm like... I have no idea how that's written.
