JavaScript is a fundamental asset for any web developer. As an evolving language, new releases continue to refine it to make it more accessible for large-scale use. ECMA Script, or ES in short, is the standardized name for the programming language popularly known as JavaScript. The sixth release of the script is known as ES6 and features major enhancements which improve Javascript's usability. Writing and reading code is now easier with the introduction of features like Arrows, Symbols, etc. 

This course provides a practical view into all of the components present in ES6. We'll discuss the importance of each component, learning how and why it makes things simpler in Javascript. Interactive exercises and quizzes will help you adopt these modern coding practices for JavaScript. ES6 is rapidly growing in popularity, and this course is essential for anyone who wants to be fully immersed into JavaScript.

JavaScript In Practice: ES6 And Beyond

A **proxy** is an object that wraps an object or a function and monitors access to the wrapped item, a.k.a. the **target**. We use proxies for the intention of blocking direct access to the target function or object.

The proxy object has some *traps* which handle access to the target. The traps are the same as the methods used in the Reflect API. Therefore, this section assumes that you are familiar with the Reflect API, as you will use the same calls. The following traps are available:

- `apply`
- `construct`
- `defineProperty`
- `deleteProperty`
- `get`
- `getOwnPropertyDescriptor`
- `getPrototypeOf`
- `has`
- `isExtensible`
- `ownKeys`
- `preventExtensions`
- `set`
- `setPrototypeOf`

Once a trap of a proxy object is executed, we can run any code, even without accessing the target. The proxy decides if it wants to provide you access to the target, or handle the request on its own. 

The available traps allow you to monitor almost any use case. Some behavior cannot be trapped though.

We cannot tell if our object is compared to another value, or wrapped by another object. We cannot tell if our object is an operand of an operator. In reality, the absence of these use cases is hardly problematic.

Now, let's learn how to define these proxies.
