I want to get balance of given address.



  var x =  web3.eth.getBalance("0x81b7E08F65Bdf5648606c89998A9CC8164397647")
.then(function (balance) {
console.log(balance.toString);
}).catch(function(e) {
console.log(e);
});
console.log(x);


It returns promise as a JSON



Promise {_40: 0, _65: 0, _55: null, _72: null}


As per web3.eth.getBalance() function I should get balance of given address but I am getting promise as result

          You might want to try parsing the JSON to handle the promise like this:



          var x =  web3.eth.getBalance("0x81b7E08F65Bdf5648606c89998A9CC8164397647")
          .then(function (result) {
          return result.json();
          }
          .then(balance) {
          console.log(balance.toString);
          }).catch(function(e) {
          console.log(e);
          });
          console.log(x);

            This is not the correct way to resolve a promise. You cannot just assign it to a variable like you are assigning it to x. You can either do it in the .then() or you can use await.
