ethereum - web3.eth.accounts returning a function -

i'm following tutorial here uses testrpc web3.js. after installing packages ethereumjs-testrpc , web3, testrpc started gives 10 available accounts , private keys.

web3 @ 1.0.0-beta.18 , ethereumjs-testrpc @ 4.1.1.

when following code run

web3 = require('web3'); web3 = new web3(new web3.providers.httpprovider("http://localhost:8545")); web3.eth.accounts 

i following output instead of 10 accounts shown in tutorial. went wrong?

accounts {   currentprovider: [getter/setter],   _requestmanager:    requestmanager {      provider: httpprovider { host: 'http://localhost:8545', timeout: 0, connected: false },      providers:       { websocketprovider: [function: websocketprovider],         httpprovider: [function: httpprovider],         ipcprovider: [function: ipcprovider] },      subscriptions: {} },   givenprovider: null,   providers:    { websocketprovider: [function: websocketprovider],      httpprovider: [function: httpprovider],      ipcprovider: [function: ipcprovider] },   _provider: httpprovider { host: 'http://localhost:8545', timeout: 0, connected: false },   setprovider: [function],   _ethereumcall:    { getid:       { [function: send]         method: [object],         request: [function: bound ],         call: 'net_version' },      getgasprice:       { [function: send]         method: [object],         request: [function: bound ],         call: 'eth_gasprice' },      gettransactioncount:       { [function: send]         method: [object],         request: [function: bound ],         call: 'eth_gettransactioncount' } },   wallet:    wallet {      length: 0,      _accounts: [circular],      defaultkeyname: 'web3js_wallet' } } 

later in tutorial, web3.eth.accounts needed when deploying contract

deployedcontract = votingcontract.new(['rama','nick','jose'],     {data: bytecode, from: web3.eth.accounts[0], gas: 4700000}) 

that tutorial written before web3.js v1 came out. api has changed in v1, including eth.accounts. can either pin older version of web3.js, 0.19.0, or find equivalent method in new v1 docs.

retrieving accounts down asynchronously, many other calls in new api. can call callback or using promises. printing list of accounts console like:

web3.eth.getaccounts(console.log); // or web3.eth.getaccounts().then(console.log); 

from web3.eth.getaccounts v1 documentation

so rewriting section referenced @ end:

web3.eth.getaccounts() .then(function (accounts) {   return votingcontract.new(['rama','nick','jose'],     {data: bytecode, from: accounts[0], gas: 4700000}); }) .then(function (deployedcontract) {   // whatever want deployedcontract... })
