When developing Web3 projects, it helps to have a local blockchain devnet for testing. Ganache is one of the most popular tools for this in the Ethereum ecosystem and part of Truffle. Ganache allows you to set up a local blockchain with different settings to thoroughly test your smart contracts before deployment.
Seeing a local blockchain’s output in the terminal helps you to understand how your project will behave in a live environment. The ability to set the output to variables to manipulate some front-end code is even more useful. Some users may not know that you can do this by running Ganache in your browser.
