In ES6, you can use the delete method to remove an item from a Map. This method takes the key as an argument and removes the corresponding key-value pair from the Map.

In ES6 object literals, the proto property is used to establish prototype delegation and achieve inheritance. The proto property allows an object to inherit properties and methods from another object, forming a prototype chain. This mechanism facilitates code reuse and promotes a more modular and extensible design. It is important to note that the proto property is considered an internal implementation detail, and using Object.create() is the recommended approach for explicit prototype delegation.

One challenge with tree shaking is the potential removal of code with side effects. If not handled carefully, it may result in unintended consequences, such as eliminating code that performs actions like setting up event listeners or initializing global variables.

Yes, methods in ES6 classes can be anonymous by omitting the method name. However, this is not a recommended practice as it makes code less readable. Naming methods helps in understanding the purpose and functionality of the methods within a class.

The correct option is Task Queue. When the call stack is occupied, new tasks are placed in the task queue to await their turn. The Event Loop manages the process of moving tasks from the task queue to the call stack. Understanding this mechanism is crucial for handling asynchronous operations effectively.

In functional programming, functions like compose or pipe are used as combinators to create a pipeline of operations by composing other functions. These are higher-order functions that take functions as arguments and return a new function that represents the composition of those functions.

Dynamic Imports in JavaScript allow for efficient code splitting. By loading only the modules that are needed at runtime, it improves the performance of the application, especially in large projects where not all code is required on every page.

Weak references in WeakMap and WeakSet enable automatic memory management by allowing the garbage collector to reclaim objects that are no longer reachable.

When a Promise is created, it starts in the "Pending" state. This means that the Promise is neither fulfilled nor rejected. It's essentially in a pending state until the asynchronous operation it represents is completed.

Unhandled exceptions in an async function result in unhandled promise rejections. This can lead to unexpected behavior or crashes if not properly addressed. It's crucial to handle errors appropriately in async functions to ensure robust and error-resistant code.
