I’ve made my way to Lesson 6 of the Learn Blockchain, Solidity, and Full Stack Web3 Development with JavaScript – 32-Hour Course by Patrick Collins which is the Hardhat Simple Storage lesson. Below is a list of things I have learned and discovered through this particular lesson.

• What Hardhat is, why you would use it and how it makes Ethereum Blockchain Development easier and more seamless

• What yarn is, how it is “different” than npm, and why you would use it instead of npm

• How to work with Hardhat inside of Visual Studio Code

• What the Hardhat Network is, how and when to use it

• How to deploy to a Testnetwork (Rinkeby in this case) with Hardhat

• How you can work with network configs to only do something (like verify a contract when it’s NOT on the Hardhat network)

• What kinds of information you can put into the Hardhat config file

• How to work with the Etherscan API

• How to work with the Coinmarketcap API

• What Hardhat tasks are and how to use them

• How Hardhat tasks and scripts are the same/different and when you would use each

• How to run a Hardhat node on your local “network” similar to what Ganache does (which we used in a previous lesson)

• What the Hardhat console is and how to use it

• Testing in solidity versus testing in a modern programming language (like Javascript)

• How to use the Mocha framework to write javascript tests for solidity code

• Assert and Expect keywords when writing tests

• What the Hardhat Gas Reporter extension is and how to use it to determine what our code’s gas costs look like

• What the Solidity Coverage Hardhat extension is and why you would use it
