Error Handling in JavaScript: Try, Catch, Finally

No matter how good your code is, errors are inevitable . What matters is how you handle them. JavaScript provides powerful tools like try , catch , and finally to manage errors gracefully—so your application doesn’t crash unexpectedly. 🚨 What Are Errors in JavaScript? Errors are problems that occur during code execution (runtime). Example: ```js id="err1" console.log(x); // ❌ ReferenceError: x is not defined ### Common Types of Errors: * **ReferenceError** → variable not defined * **TypeError** → wrong type usage * **SyntaxError** → invalid code --- ## 😵 The Problem Without Error Handling ```js id="err2" function divide(a, b) { return a / b; } console.log(divide(10, 0)); console.log("This may still run..."); Some errors can break your app or cause unexpected behavior. 💡 Using try and catch The try...catch block lets you handle errors safely . ```js id="try1" try { let result = riskyFunction(); console.log(result); } catch (error) { console.log("Something went wrong:", error.message); }
