Functions Development Tutorials, Guides & Insights

• Accessing Properties:
• Dot notation:

    console.log(person.name); // "Alice"

• Strings: Text, enclosed in quotes ("Hello", 'Hello').
• Numbers: Numerical values (100, 3.14).
• Booleans: True or false values (true, false).
• Arrays: Collections of values ([1, 2, 3]).
• Objects: Key-value pairs ({name: 'John', age: 30}).

Variables store data that can be used and updated later. In JavaScript, you can declare variables using let, const, or var.

interface MyInterface {
    function setData(uint _data) external;
    function getData() external view returns (uint);
}

contract MyContract is MyInterface {
    uint private data;

    function setData(uint _data) external override {
        data = _data;
    }

    function getData() external view override returns (uint) {
        return data;
    }
}

Libraries are similar to contracts but are meant to hold reusable code. They cannot hold state.
