When I'm working whit web3 I have something like:

 var abi = [...];
var contract = new web3.eth.Contract(abi,"0x86Fa049857E0209aa7D9e616F7eb3b3B78ECfdb0");

then I use something like:


In truffle test I have a contract instance in hand, and I use


without the "methods" indirection, what is different from the two contract instances?


The difference is that Truffle injects Web3.js 0.20 into the test script, whereas you are working with Web3.js 1.0.

  • in this case, which is best to learn and use? latest Web3.js ? – KitKarson May 30 '18 at 2:12
