JavaScript was initially designed to make web pages more interactive. It allowed developers to create dynamic and engaging web content by manipulating elements on web pages in response to user actions. This interactivity revolutionized web development.

To handle exceptions within a "for" loop, you can wrap the entire loop in a try-catch block. This allows you to catch and handle exceptions that occur during the loop's execution, preventing it from being terminated prematurely. The other options do not directly address exception handling within the loop.

Arrow functions behave differently from regular functions when it comes to the "this" keyword. They inherit the "this" value from their containing lexical (surrounding) scope, while regular functions have their "this" determined by how they are called. This behavior can be advantageous in certain situations.

The "call" method in JavaScript is used to bind an object's context to a function and is called immediately. It allows you to specify the value of "this" explicitly when invoking a function, along with any additional arguments you want to pass to the function.

To select all

elements within a specific parent element, you can use the querySelectorAll() method on the parent element. This method allows you to specify the CSS selector within the context of the parent element, ensuring that only

elements within that parent are selected. The other options are incorrect for this purpose.

To prevent script injection attacks, it's crucial to use the textContent property to set content dynamically. Unlike innerHTML, which parses and executes scripts, textContent treats input as plain text, reducing the risk of script injection. Using libraries may help but doesn't guarantee security. innerText has limited browser support.

You can utilize closures in JavaScript to maintain state between function calls without relying on global variables. A closure is a function that has access to variables from its outer (enclosing) function's scope, even after the outer function has finished executing. This allows you to create private variables and maintain state within the closure function.

Closures in JavaScript are often used for encapsulation. They allow variables and functions to be "enclosed" within a function, preventing them from polluting the global scope and providing a level of data privacy. This enables code organization, reduces naming conflicts, and promotes modularity in your programs. Closures are a key feature in achieving encapsulation in JavaScript.

In JavaScript, prototypes are often utilized by assigning a constructor function to an object's prototype property. This constructor function serves as a blueprint for creating objects with shared properties and methods. The prototype object associated with this constructor contains those shared properties and methods.

In Internet Explorer, the attachEvent() method is used to attach event listeners. This method is specific to Internet Explorer and serves a similar purpose to addEventListener() in other browsers, allowing you to respond to events such as clicks and keypresses.
