The way you write the constructor is now deprecated, it should now be:
constructor() public {
// ...
}

[ManWalkInNature]

Great work! But I have some questions anyways.
Does it still work for now? (3 year later) Because I have some errors like "function name and contract name cant be same" But in this video these are same. It was just an example. I want to work updated versions but there are some difference which are prevent working my smart contract. Have you any advice for me?

Hi, I'm new to this apsect so I want to ask something.
does this tutorial still work atm because when I download the truffle init, the file is different. thank you

[babasahebpinjar]

Hi Gregory, First of all I have to tell that you have made a great tutorial. I am not able to pass this test

1) Contract: D transfers token ownership:
AssertionError: error message must contain revert
at test/BabaCoin.js:44:8
at <anonymous>
at process._tickCallback

This is my code

it('transfers token ownership', function() {
return {
tokenInstance = instance;
// Test `require` statement first by transferring something larger than the sender's balance
return tokenInstance.transfer.call(accounts[1],
{
>= 0, 'error message must contain revert');
});
})



function transfer(address _to, uint256 _value) public returns (bool success) {
require(balanceOf[msg.sender] >= _value);
}
}
