Here’s the things that I learned during the Remix FundMe section of the Learn Blockchain, Solidity, and Full Stack Web3 Development with JavaScript – 32-Hour Course.

• Using ChainLink oracles

• Using ChainLink data feeds

• Importing a ChainLink contract into solidity directly

• How do do ETH Math (decimals don't work to do math in solidity)

• What returns / return are and when to use them

• What msg.sender and msg.value are and do

• What a library is and how it's different than a contract

• What safeMath is and what it used to be used for

• Solidity By Example website

• The structure and syntax of For loops in Solidity

• Constructors in Solidity and why they matter

• Single equals (assigns), versus double equals (checks)

• What modifiers are and how they work

• What the Constant and Immutable Keywords are and why you would use them

• Deployed a contract to the Rinkeby Ethereum Testnet that accepted funding and allowed funders to withdraw from the contract!
