Error Boundaries in Practice

Isolate failures

Wrap independent features in separate try/catch blocks. If one feature fails, others keep working.

function initApp() {
  try { initAnalytics(); } 
  catch (e) { console.warn("Analytics failed"); }
  
  try { initChat(); } 
  catch (e) { console.warn("Chat failed"); }
  
  // Core features
  initAuth();
  initUI();
}

Non-critical failures shouldn't break critical features.
