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); }
