Pragma Directive
Solidity and Blockchain is an ever evolving space, that’s why many updates and breaking changes are made very often compared to any other technologies that’s why it offers this feature to avoid compatibility issues.
- Pragma is a directive that is followed by the version selection operator ‘^‘ and the version number. It defines the solidity compiler’s version that this code will be compiled on.
- It helps avoid compatibility issues as updates are made frequently.
Example:
pragma solidity ^0.8.25;
This defines that the smart contract will use solidity version >= (greater than equal to) 0.8.25.
Unlock the Power of Solidity: Exploring the Essential Keywords for Smart Contract Development
Solidity is a smart contract programming language built solely to develop smart contracts that can be deployed on blockchains. C++ and JavaScript inspired it, an Object Oriented and High-Level language (HLL), that helps developers define the behaviour and rules for a Decentralized Application (Dapp). Smart contract facilitates autonomous, secure, and efficient transaction execution on the blockchain without needing any intermediary (self-executable) and solidity provides the base framework for achieving the same.
It is essential to understand the common keywords used in solidity to solidify your core understanding of the language so in this article, we’ll pin down some prominent keywords that help us develop these smart contracts by embracing the true power of solidity language.
