I'm looking at some javascript code that does this:

const senderPubKey = (0, secp256k1_1.ecdsaRecover)(signature, recovery.toNumber(), msgHash);

I don't understand this syntax. When I do console.log(secp256k1_1.ecdsaRecover) I get [Function: ecdsaRecover] so I'm guessing it's a function call but why not do secp256k1_1.ecdsaRecover(signature, recovery.toNumber(), msgHash)?
