The following types are also called value types because variables of these types will always be passed by value.
Transactions that happen in a smart contract are processed by the blockchain, which means they can be sent automatically without a third party.
Right after the pragma statement wij have an import statement. This imports existing code into our smart afspraak.
Stack: hold small local variables and is almost free to use, but can only hold a limited amount ofwel values
Review: view and pure functions are read-only and don't change state on the blockchain. They also don't cost any gas, and the user won't be prompted to sign a transaction with copyright.

Once a program kan zijn deployed to the Ethereum Network these computers, also known as nodes, will make sure it kan zijn executed as written. Ethereum kan zijn the infrastructure for running D apps worldwide. It’s not a currency but it’s a platform. The currency used to incentivize the network is called Ether.
The demand for Web3 developers is skyrocketing, and so are the salaries. Companies, blockchain startups, and enigszins established tech giants are seeking skilled developers who can navigate the decentralized landscape with ease.
The way to send Ether along with a function kan zijn simple, with one caveat: we need to specify how much to send in wei, not Ether.
How could wij give that information to our smart contract? Putting all those values in it would be wasteful. It would also mean wij need to add genoeg code to work out which blockchain the overeenkomst kan zijn running on.

In some situations, you can have an abstract contract which kan zijn similar to but different from an interface.
In the Transaction.jsx file, we’ll carry out our transactions. wij’ll offer a transactional bediening that allows users to carry out several transactions on the blockchain application using the Ethereum network:
jsx component is displayed at the front page ofwel our application, housing all the frontend displays that are shown to the user on our landing page, like our form, wallet, and others:
