For & While Loops in Solidity | Learn Solidity (0.8) - By Example

In this beginner-friendly Web3 tutorial, you'll learn how to use for and while loops effectively in Solidity smart contracts. We’ll walk you through clean examples using control flow tools like continue and break—plus teach you why unbounded loops can be dangerous due to Ethereum’s gas limits! 💡 What You’ll Learn: 🟡 How to write for, while, and do-while loops in Solidity 🟠 When to use continue and break 🔵 Why loops must be gas-safe in smart contracts 🧠 Tips to avoid high gas usage and failed transactions 🧪 How to log loop execution using Solidity events in Remix IDE 🛠️ Tools & Stack: Language: Solidity 0.8.x IDE: Remix Ethereum IDE Network: EVM-compatible (Ethereum, Polygon, etc.) ⚙️ Use Cases: ✅ Filtering logic in DApps ✅ Controlled execution of repetitive tasks ✅ Looping over fixed-length data ✅ Event logging for debugging and testing 📺 Related Videos: https://youtu.be/j5O7B2R4My4 https://youtu.be/wVWkMaCTNkc https://youtu.be/eBa837JnMNA 🔔 Follow & Subscribe: Made by @dAppSmartDev — hands-on Web3 tutorials that help developers move from Web2 to Web3 with clarity and confidence. 👍 Like · 💬 Comment · 🔔 Subscribe for weekly Solidity, Ethereum & blockchain dev content. 🏷️ Hashtags: #Solidity #SmartContracts #Web3 #Ethereum #BlockchainDevelopment #SolidityTutorial #ForLoop #WhileLoop #LearnSolidity #CryptoDeveloper #GasOptimization #DappDevelopment #ControlFlow #RemixIDE #EVM
