Having finished this section, you may feel that accessing `bitcoind` via `curl` is very much like accessing it through `bitcoin-cli` ... but more cumbersome. And, you'd be right. `bitcoin-cli` has pretty complete RPC functionality, so anything that you do through `curl` you can probably do through `bitcoin-cli`.
_What is the power of curl?_ Most obviously, `curl` takes out one level of indirection. Instead of working with `bitcoin-cli` which sends RPC commands to `bitcoind`, you're sending those RPC commands directly. This allows for more robust programming, because you don't have to worry about what unexpected things `bitcoin-cli` might do or how it might change over time. However, you're also talking your first steps toward using a more comprehensive programming language than the poor options offered by a shell script. But for that, you'll need to use a `curl` library within a more familiar language like JavaScript or C. In other words, command-line `curl` was just the first step, the basis to better explain what you're doing as you move forward.
