js function reminder

arrow 1

• function and const functions are almost the same.
• async function greeter(greeting, name) {} - same as
• const greeter = async (greeting, name) => {} - same as
• async (greeting, name) => {}

arrow 2

• preferred:describe("hello", function() {})
• not preferred: describe("hello", () => {})

dealing with nested imports

given this tree structure

📦test ┗ 📜test-deploy.ts
📦typechain-types ┣ 📂factories ┃ ┣ 📜SimpleStorage__factory.ts ┃ ┗ 📜index.ts ┣ 📜SimpleStorage.ts ┣ 📜common.ts ┣ 📜hardhat.d.ts ┗ 📜index.ts

I want import { SimpleStorage__factory, SimpleStorage } from "../typechain-types" in test-deploy.ts

SimpleStorage__factory

1. in 📦typechain-types > 📂factories > 📜SimpleStorage__factory.ts => export class SimpleStorage__factory
2. in 📦typechain-types > 📂factories > 📜index.ts => export { SimpleStorage__factory } from "./SimpleStorage__factory";
3. in 📦typechain-types > 📜index.ts => export * as factories from "./factories"; & export { SimpleStorage__factory } from "./factories/SimpleStorage__factory";

SimpleStorage

1. in 📦typechain-types > 📜SimpleStorage.ts => export interface SimpleStorage
2. in 📦typechain-types > 📜index.ts => export type { SimpleStorage } from "./SimpleStorage";

function export + destructure

async function deploy(hre) {
  const namedAccounts = hre.getNamedAccounts,
    deployments = hre.deployments;
}
module.exports.default = deploy();

same as

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

same as

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