NEW QUESTION # 55
Which tag is required when importing the jQuery library?

  • A. Section
  • B. Body
  • C. Script
  • D. meta

Answer: C

Explanation:
The <script> tag is required when importing the jQuery library into an HTML document.
* Including jQuery:
* Purpose: The <script> tag is used to embed or reference executable code (JavaScript).
* Example:
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
* Explanation:
* The <script> tag should be placed in the <head> or at the end of the <body> to ensure that the library is loaded before the scripts that depend on it.
* References:

NEW QUESTION # 56
Which programming paradigm best describes JavaScript?

  • A. Function-driven
  • B. Event-driven
  • C. Object-based
  • D. Object-oriented

Answer: C

Explanation:
JavaScript is often described as an object-based language, meaning it is centered around objects. While it supports object-oriented programming (OOP) concepts, it is more accurate to describe it as object-based due to its prototypal inheritance model rather than classical inheritance.
* Object-Based: JavaScript is built around objects and supports the creation and manipulation of objects.
* Object-Oriented Features: JavaScript supports OOP principles like encapsulation, inheritance, and polymorphism, but through prototype chains rather than class-based inheritance.
* Functional and Event-Driven: JavaScript supports functional programming and is often used in an event-driven manner, particularly in the context of web browsers.
References:
* MDN Web Docs on JavaScript Object Model
* W3C JavaScript Overview


NEW QUESTION # 57
Which attribute displays help text in an input field without specifying an actual value for the input?

  • A. Placeholder
  • B. name
  • C. For
  • D. Default

Answer: A

Explanation:
The placeholder attribute in an <input> element displays help text in the input field without specifying an actual value for the input. This text disappears when the user starts typing.
* Placeholder Attribute: This attribute provides a hint to the user about what type of information is expected in the field.
* Usage Example:
<input type="text" placeholder="Enter your name">
The input field will show "Enter your name" as help text.
References:
* MDN Web Docs on placeholder
* W3C HTML Specification on Input Placeholder


NEW QUESTION # 58
Given the following javaScript code:

Which code segment calls the method?

  • A. Obj,sayHello;
  • B. Window,sayhello();

Answer: A

Explanation:
To call the sayHello method in the given JavaScript object, you need to use the object's name followed by the method name with parentheses.
* Correct Method Call:
* Given the object definition:
var obj = {
sayHello: function() {
alert("Hello");
}
};
* To call the method sayHello on the object obj:
obj.sayHello();
* Explanation:
* Option A: Obj.sayHello; is incorrect syntax. The correct syntax is obj.sayHello();.
* Option B: Window.sayHello(); is incorrect because the method is defined in the obj object, not the window object.
* References:
* MDN Web Docs - Functions
* W3Schools - JavaScript Objects


NEW QUESTION # 59
Which structure tag should a developer use to place contact information on a web page?

  • A. <footer>
  • B. <Aside>
  • C. <Main>
  • D. <Nav>

Answer: A

Explanation:
The <footer> tag is used to define a footer for a document or a section. A footer typically contains information about the author of the document, contact information, copyright details, and links to terms of use, privacy policy, etc. It is a semantic element in HTML5, which means it clearly describes its meaning to both the browser and the developer.
* Purpose of <footer>: The <footer> element represents a footer for its nearest sectioning content or sectioning root element. It typically contains information like:
* Contact information
* Copyright information
* Links to related documents
* Information about the author
* Usage Example:
<footer>
<p>Contact us at: [email protected]</p>
<p>&copy; 2024 Example Company</p>
</footer>
In this example, the <footer> tag encloses contact information and copyright details.
* Semantic Importance: Using semantic elements like <footer> enhances the accessibility of the document and provides better context for search engines and other user devices.
References:
* MDN Web Docs on <footer>
* W3C HTML5 Specification on <footer>
