Lets look the events of Open Zeppelin’s ERC20 token contract:

ERC-777 is difficult to implement properly, due to its susceptibility to different forms of attack(opens in a new tab). It is recommended to use ERC-20 instead. This page remains as a historical archive.

One of the most common IDE for writing smart contracts is the remix IDE hosted on ethereum.org. This is the fastest way to get started with writing Smart contracts with solidity. It comes with all you need, a web browser-based compiler and about 15 free Ethereum account loaded with 100eth coin. These coins are on the Testnet not the Mainnet so don't even think of spending them🙄.
