What is the difference between Java EE and Java SE?
Java EE (Enterprise Edition) and Java SE (Standard Edition) are both versions of the Java programming language, but with different feature sets. Java EE is built for enterprise applications, and contains a large set of libraries for connecting to enterprise systems such as databases and web services. It also includes the latest enterprise features such as messaging and distributed computing. Java SE is the base edition of the Java language and is designed for general purpose programming. Java SE contains a limited set of libraries, and it is intended to be used as a starting point for developing applications.

What is WebAssembly and why is it better than JavaScript?
WebAssembly (WASM) is a low-level programing language designed to be faster and more efficient than traditional JavaScript code. It allows developers to write code in portable, compile-able formats, which can then be run across multiple platforms, irrespective of the underlying architecture. It is designed to improve the performance of web applications, particularly on low-resource devices like smartphones. Compared to JavaScript, WASM code runs up to 20x faster, with its binary format allowing for faster loading times and complex calulations. The WASM execution model is much more secure since it is a sandboxed execution environment, ensuring that code runs in a safe, isolated environment.

How are arguments passed in JavaScript?
In JavaScript, arguments are passed by value. This means that when a function is called with arguments, each argument's value is copied into the function's execution context. Changes made to the arguments within the function's scope are not reflected outside the function.

How to retrieve all arguments passed to a function in JavaScript?
There are two ways to retrieve all arguments passed to a function in JavaScript:
1. The "arguments" object - This is an array-like object that holds all of the arguments passed to a function. We can access the arguments with the "arguments" keyword followed by the index of the argument we want. For example:
let myFunction = function() {
console.log(arguments[2]);
}
myFunction('foo', 'bar', 'baz'); // Prints 'baz'
2. The Rest Parameters - This is a newer syntax that was added in ES6 that allows us to capture all of the arguments passed to a function in one variable. For example:
let myFunction = function(...args) {
console.log(args);
}
myFunction('foo', 'bar', 'baz'); // Prints ['foo', 'bar', 'baz']
