Ethereum Dapp Development There is a difference from the traditional application development, is that you call the contract method is sometimes not free, need to pay gas. So, how much gas should be consumed when sending a transaction or invoking a contract method? In Ethereum, use the Estimategas () method to estimate the gas consumption that a trade consumes. We

. The following compares its advantages and disadvantages: Advantage: assembly languages can express very underlying things. Registers and I/O can be directly accessed; The code can be executed very accurately; You can compile code that is more efficient than the general compiling system; It can be used as an interface of different languages or standards. Disadvantage: assembly language is a very low-level language. It is very lengthy and monotonous, and can be realized during programming

We can use the Estimategas function of the web3.js framework to obtain a gas estimate for an Ethereum smart contract by executing a message call or transaction that executes directly in the VM of the node, not confirmed in the blockchain, and returns the estimated gas amount used.Function call:Web3.eth.estimateGas (CallObject [, callback])Parameters:In Web3.eth.sendTransaction, the parameters are mostly opt
