Updated enterRaffle() logic

[stevegee1]

To avoid redundancy of the addresses in the array, s_players, if msg.sender calls the enterRaffle() multiple times:

• we check if the address has already entered the raffle before calling enterRaffle() using mapping(address => uint256(i.e msg.value)): if true ? increment s_addressToValue[msg.sender] with the msg.value: increment msg.value && s_players Hence, we only have unique addresses as indices in our s_players array

I love your PFP.

Going to close to keep the code as similar to the video as possible, but you're right!! This function could use an improvement like this!
