Cisco Javascript Essentials 2 Answers -

Example:

Example:

try { // Code that may throw an error } catch (error) { console.error('Error:', error.message); } finally { console.log('This code always runs'); } Answer: Functions in JavaScript are blocks of code designed to perform a specific task. A JavaScript function is executed when it is invoked (called).

Example:

function greet(name) { return `Hello, ${name}!`; } console.log(greet('Alice')); // Output: Hello, Alice! Answer: An object in JavaScript is an entity with properties and types. Objects can contain many properties and can be used to represent complex data structures.

let person = { firstName: 'John', lastName: 'Doe', greet: function() { console.log(`Hello, my name is ${this.firstName} ${this.lastName}.`); } }; Cisco's JavaScript Essentials 2 course covers a wide range of topics from the basics of JavaScript to more advanced concepts. Understanding these fundamentals of JavaScript—variables, data types, functions, objects, and error handling—enables developers to build dynamic and interactive web applications. As JavaScript continues to evolve, staying updated with its ecosystem and best practices becomes crucial for web development.
