For...of loops are preferred when working with asynchronous code because they automatically handle Promise resolution. When you iterate over an iterable that contains Promises, for...of will await each Promise and provide the resolved value, making it more convenient for working with asynchronous operations.

The primary difference is that in a while loop, the condition is checked before executing the code block. If the condition is initially false, the code block may never run. In contrast, the do-while loop guarantees that the code block is executed at least once because it checks the condition after executing the block. This makes do-while useful when you want the code to run once before checking the condition.

The Equality (===) operator can be used to compare both value and type in JavaScript. It checks if two values are strictly equal, meaning they have the same value and the same data type. The other options, such as Assignment (=) and Identity (==), do not perform strict value and type comparison. Inequality (!=) checks for inequality.

Inheritance is the process by which an object inherits properties and behaviors (methods) from its prototype or parent object. JavaScript uses a prototype-based inheritance model, where objects inherit from other objects, and this is a fundamental concept in the language.

The blob() method is used to read a Response stream and return it as a blob object. This is commonly used when dealing with binary data or files. The other options (text(), json(), arrayBuffer()) are used for different types of Response data processing.

One potential reason for a webpage hang caused by a "for" loop is excessive DOM manipulation within the loop, which can block the main thread. To solve this, consider moving DOM manipulation outside the loop or optimizing the DOM operations. An infinite loop, missing loop condition, or insufficient memory allocation could also cause hangs but are less likely in this context. JavaScript Debugging

Lexical scoping in JavaScript refers to the way variable scope is determined by the placement of variables in the source code. Variables declared inside a function are accessible within that function, creating a hierarchy of scope. This helps prevent variable conflicts and promotes clean code.

The statusText property of the Response object represents the status text of the HTTP response. It provides a textual description of the HTTP status code, such as "OK" for status code 200 or "Not Found" for status code 404. This property is useful for understanding the meaning of the response status code in a more human-readable form.

The arithmetic operator '++' is known as the increment operator. It increases the value of a variable by 1. For example, if you have a variable x and you write x++, it will increment the value of x by 1. This is commonly used in loops and counters in JavaScript.

You can create a new HTML element in JavaScript using the createElement() method. This method is used to dynamically generate HTML elements in your code. It takes the name of the HTML tag you want to create as an argument.
