#reactjs #html #css #htmlcss #javascript #webdevelopment #coding. #shorts . . . . . . Error Explanation: The code throws a ReferenceError because y is used in the default parameter x = y before it's defined. Why It Fails: Default parameters are evaluated left-to-right, so when x = y runs, y is still in the Temporal Dead Zone (TDZ). Fix:Swap the order: function log(y = 10, x = y) { ... } Output: 10 10 (works correctly).

Explanation 👇👇 This code involves async/await and error handling with try...catch. Let's break it down step by step: 👉 What happens inside foo(): The function calls Promise.reject("Error!"), meaning it returns a rejected promise. However, the rejection is not caught inside the try...catch block because return does not trigger the catch block in async functions. The catch block only runs if there's an explicit throw inside the try. 👉 What foo().then(console.log) does: foo() returns a rejected promise with "Error!". Since there's no error handling inside foo(), the rejection propagates to .then(console.log), but because .then() does not handle rejections, it won't change the rejected value. The rejected value "Error!" is logged. 👉 Final Output: Option B) "Error!" Happy Coding ✌️ #coding #javascript #js #code #programming #webdevelopment #codeclash
