What DevTools feature would help identify exactly where and when the user object was modified?
function processUser(user) {
console.log(user);
// Many lines of complex code
updateUserEmail(user);
// More complex code
console.log(user); // Why did the email change here?
}
Object property breakpoints are ideal for this scenario: 1) They allow setting a breakpoint that triggers when a specific property of an object is accessed or modified, 2) In Chrome DevTools, you can right-click on an object in the console and select 'Break on property access/modifications', 3) This would pause execution exactly when the user's email property changes, 4) The call stack would show which function made the modification, 5) This is far more precise than using console.log() to track changes, 6) It works even if the property is modified deep within a call chain, 7) The debugger pauses in real-time when the property changes, providing the exact execution context, 8) This feature is invaluable for tracking unexpected state mutations in complex applications.
