Lesson 7 Syntactic Sugar

[Phasor]

Apparently lines (10 + 11) and 12 are the same in the below.

I understand the more verbose syntax. getNamesAccounts() and deployments() are coming from the hre. However, in line 12, how does JS know where to get the getNamedAccounts() and deploymenys() functions from?

the hardhat-deploy pluging is pretty clever! When we call yarn hardhat deploy it automatically sticks the hardhat runtime environment (or hre) as an input parameter to our module.exported async function.

We then, pull out getNamedAccounts, deployments from the hre.

You can think of it like

module.exports = async(hre) => {

And hardhat-deploy is sticking in the hre object. But we don't want everything, so we just pull out those two

module.exports = async ({getNamedAccounts, deployments}) => {
