Why does module.exports = function require no () after the exported function?

[gmluqa]

Context is during the fund me hard hat lesson, for yarn hardhat deploy , we use something along the lines of:
function deployFunc() { console.log("Hello"); }
module.exports = deployFunc;

Why isn't it module.exports = deployFunc(); instead? Isn't this a function call?

Great question!

So we are exporting the deployFunc function, we are next exporting the return value of deployFunc

We want hardhat to call deployFunc, we don't want hardhat to call whatever deployFunc has already returned. Let me know if that makes sense.

To really see, try exporting as you have said!
