Cisco JavaScript Essentials 2 Answers
Q9: What is the output order?
console.log("1");
setTimeout(() => console.log("2"), 0);
Promise.resolve().then(() => console.log("3"));
console.log("4");
A: 1, 4, 3, 2
Explanation: Microtasks (Promises) run before macrotasks (setTimeout). Sync code runs first, then microtasks, then macrotasks.
Q10: Given an async function:
async function getData()
return 42;
console.log(getData());
A: Promise 42 (Not 42). Async functions always return a Promise.
Q11 (Exclusive Answer): Which correctly handles multiple promises concurrently?
A: B. Promise.all runs them concurrently. Option A runs them sequentially.
Cisco JavaScript Essentials 2 is a comprehensive course that covers the basics of JavaScript programming. The course is designed to provide learners with a solid understanding of JavaScript fundamentals, including data types, functions, loops, and object-oriented programming.
Q1: Which method creates a new array with results of calling a provided function on every element?
Q2: Consider the code: let p = new Promise((resolve, reject) => reject("Error"); );. How do you handle the error?
Q3: What is the output of console.log(2 + "2");?
Q1: What is the output of the following code?
let sum = (a, b = 5) => a + b;
console.log(sum(2, 0));
A: 2
Explanation: Default parameters are overwritten if an argument is provided. Here, 0 replaces the default 5, so 2 + 0 = 2.
Q2: Which statement correctly uses the rest parameter to collect all arguments into an array?
// Option A: function collect(...args) return args;
// Option B: function collect(args...) return args;
// Option C: function collect(...args...) return args;
A: Option A (function collect(...args))
Q3 (Exclusive Scenario): Given a recursive function that calculates factorial:
function fact(n)
if (n <= 1) return 1;
return n * fact(n - 1);
What happens when fact(100000) is called? Answer: b) A client-side programming language
A: C. Recursion depth exceeds the call stack limit.
