Learning Angular 2 Directives (Video 2)

This video tutorial introduces key ES6 features and their implementation in Angular projects. It covers setting up a development environment using TypeScript, the use of arrow functions, and the concept of modules and imports in ES6. The tutorial also explains how to execute TypeScript and ES6 code in browsers using SystemJS.

What is the primary purpose of using transpilers in modern JavaScript development?

• To debug JavaScript code more efficiently

• To add new features to JavaScript

• To enhance the speed of JavaScript execution

• To convert ES6 code into ES5 code for browser compatibility

Which of the following is a key feature of ES6 that simplifies function syntax?

• Traditional functions

• Anonymous functions

• Arrow functions

• Callback functions

What problem do arrow functions solve in JavaScript?

• They provide a more concise syntax for functions

• They allow for asynchronous programming

• They ensure 'this' keyword points to the correct context

• They improve the performance of JavaScript code

How do ES6 classes improve code readability compared to ES5?

• By eliminating the need for functions

• By allowing multiple inheritance

• By providing a more natural and understandable structure

• By using a more verbose syntax

What is the purpose of the 'export' keyword in ES6 modules?

• To execute a module immediately

• To delete a module

• To make a module available for import in other files

• To hide a module from other files

Which tool is used to load ES6 modules in the browser?

• Node.js

• SystemJS

• Babel

• Webpack

What advantage does TypeScript provide when working with ES6 modules?

• It allows for dynamic typing

• It eliminates the need for transpilers

• It provides auto-completion and refactoring support

• It speeds up code execution
