WGU Web Development Applications Sample Questions (Q76-Q81):

NEW QUESTION # 76
Which programming paradigm best describes JavaScript?

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

Answer: A

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.

* W3C JavaScript Overview

NEW QUESTION # 77
Which code segment contains a conditional expression?

A. `var result = aCount * 1000 == 3000000;`
B. `var result = dataCount;`
C. `var result = count > 10 ? "Done" : getResult();`
D. `var result = count++ > 10;`

Answer: C

Explanation:
> "The conditional (ternary) operator `? :` is a shortcut for an `if...else` statement. It is the only operator in JavaScript that takes three operands: a condition followed by a question mark (?), an expression to execute if the condition is true, and another expression if false." Example:
```javascript
var result = condition ? value1 : value2;
```

* ECMAScript Specification: ConditionalExpression

NEW QUESTION # 78
Which property should a developer use to change the position of an element?

A. backface-visibility
B. transform-origin
C. perspective-origin
D. transform-style

Answer: B

Explanation:
> "The `transform-origin` CSS property sets the origin for an element's transformations (e.g., rotation or scaling). This point defines the position around which the element is transformed." This means if a developer wants to change the center point of rotation or scaling, they should use `transform- origin`.

NEW QUESTION # 79
What is the process for JavaScript from validation?

A. Form fields are validated as me user inputs data after form data is sent to the server.
B. User input is sent to the server as fields are completed for validation.
C. Form fields are validated after the form is submitted but before form data is sent to the server
D. User input is sent to the server after the form is completed tor validation.

Answer: C

Explanation:
JavaScript form validation typically occurs after the form is submitted but before the form data is sent to the server. This allows the client-side script to check the input data and prevent the form from being submitted if the data is invalid.
* Client-Side Validation:
* Before Form Submission: JavaScript validates the form fields after the user attempts to submit the form.
* Prevent Default Submission: If the validation fails, JavaScript can prevent the form from being submitted and display appropriate error messages.
* Usage Example:
document.getElementById("myForm").addEventListener("submit", function(event) { var isValid = true;
// Perform validation checks
if (!isValid) {
event.preventDefault(); // Prevent form submission
alert("Please correct the errors.");
}
});
This example prevents form submission if the validation fails.

* MDN Web Docs on Form Validation
* W3C HTML Specification on Form Submission

NEW QUESTION # 80
What represents the value of the `pattern` attribute of an input element in an HTML form?

A. A regular expression
B. A style sheet
C. A JavaScript function
D. A SQL statement

Answer: A

Explanation:
> "The value of the `pattern` attribute must be a valid regular expression. This expression defines what input is considered valid."
> Used for input validation directly in HTML without relying on JavaScript.

* MDN Web Docs: pattern attribute
