Hello World
This is probably the simplest possible Tact program. It will provide callers with the classic output "hello world".
Tact lets you write smart programs. This code defines a single contract named HelloWorld.
Smart programs must be deployed to the blockchain network to be usable, try to deploy this contract by pressing the Deploy button.
Contract deployments usually cost gas. This website deploys to an emulator of TON blockchain, so gas is emulated TON coin (which is free).
If you're unfamiliar with terms like contract, deployment and gas, please read this post first. It's a great introduction to all blockchain terminology you will need to learn Tact.
A simple interaction
Contracts can have getters like greeting(). Getters are special external interface functions that allow users to query information from the contract. Try to call the getter by pressing the Run button. Calling getters is free and does not cost gas.
