Hey @MasterofBlockchain the deployer in this statement `const response = await FundMe.getAddressToAMountFunder(deployer)` is the same deployer here `deployer = (await getNamedAccounts()).deployer` i.e. the account that deployed the FundMe contract when we linked them in this statement `FundMe = await ethers.getContract("FundMe", deployer)`

I understand what is a deployer but what i don't understand is how its helping us in the function?

And same deployer question about mentioned line.

it("adds funders to funder array", async function () {
            await FundMe.fund({ value: sendValue })
            const funder = await FundMe.getFunder(0)
            assert.equal(funder, deployer)

i understand all the test but does not get assert.equal(funder, deployer) this line with deployer how deployer is helping us to test?

sorry for stupid questions. but need to know :)

We need to see that the person who originally sent ETH, in this case 'deployer' is actually pushed in the funders[] array. FundMe.fund({value:sendValue}) is chained to the deployer account so the transaction is made with the deployer address and therefore the deployer address is pushed into the funders array. funder = await FundMe.getFunder(0) is supposed to return the first entry in the funders[] and should return the expected address i.e the deployer's address.

And don't worry about the question being stupid or not :) You are doing good 👍🏽
