From a quick look at the "What is Composition API?" question in the FAQ[1], I would say:

- Reactivity API - yes, with $: labels

- Lifecycle hooks - yes, similar to the ones mentioned

- Dependency injection - not sure what it is exactly as I'm not familiar with Vue, but I don't think Svelte has a concept like this

It's poorly named (holdover from earlier version of vue when svelte didnt exist and react didn't have contexts), but it's basically React/Svelte context API for passing data to children further down the tree instead of passing them through props or through a separate state management solution (e.g. vuex/redux).

There's some nuance, but roughly:

- getContext = provide

- setContext = inject
