Failed to call web3.utils.sha3 on truffle console

Question

I try to call

web3.utils.sha3('234');

on truffle console. However I got an error:

TypeError: Cannot read property 'sha3' of undefined

Does this mean web3.utils.sha3 has not supported yet?

Answer 1

It appears you're trying to use the web3.js 1.0 syntax of web3.utils.sha3(string) but the latest version of truffle actually uses web3 0.20.1 which has the syntax web3.sha3(string [, options]). Try that instead.
