NEW QUESTION # 32
You define the Pet class as follows:
class Pet {
constructor(name, breed) {
this.name = name;
this.breed = breed;
this.show = function() {
var text = " < p > Your pet ' s name is " + name + " . The pet ' s breed is " + breed + " . < /p > " ; return text;
};
}
}
You need to derive a Dog class from the Pet class.
Complete the code by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Answer:
Explanation:
Explanation:
First blank: class Dog extends Pet {
Second blank: super(name, breed);
The correct syntax for deriving one JavaScript class from another is extends, so the derived class declaration must be class Dog extends Pet {. This creates Dog as a subclass of Pet, allowing Dog instances to inherit members defined by the Pet constructor, including name, breed, and the show() function assigned inside the parent constructor. Inside a derived class constructor, super() must be called before using this. The call super (name, breed); invokes the parent Pet constructor and passes the values required to initialize the inherited name and breed properties. Pet(name, breed); is incorrect because a class constructor cannot be invoked like a normal function. Pet.constructor(name, breed); is also incorrect because it does not call the parent constructor for the current instance. After super() runs, the Dog constructor can safely assign subclass-specific properties such as price and gender. References/topics: JavaScript classes, inheritance, extends, derived constructors, super(), custom class creation.
NEW QUESTION # 33
Which two code segments declare a JavaScript method? Choose 2.
Answer: A,C
Explanation:
The correct selections are B and C because both define a function as a member of an object context, which is the essential JavaScript pattern for declaring a method. MDN defines a method as a function that is a property of an object. It also shows that a function expression can be assigned to a variable or property and then invoked later. In option B, Score: function() { ... } represents an object-literal method property. This pattern is commonly used when defining custom objects, prototypes, configuration objects, or class-like structures in JavaScript. In option C, this.Score = function() { ... } assigns a function to the current object instance, creating an instance method that can be called through that object. Option A does not declare a method; as written, it is only an invalid or incomplete variable assignment and does not use the function keyword or method syntax.
Option D invokes Score() and assigns its return value to a; it calls a function rather than declaring a method.
References/topics: JavaScript custom classes, object members, function expressions, object-literal methods, instance methods.
NEW QUESTION # 34
A form has four buttons with a class of item. You need to apply an event listener to all buttons to invoke the moveElement function when a button is pressed. Your code must ensure bubble capture.
Complete the markup by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Answer:
Explanation:
Explanation:
First drop-down: " click " ,
Second drop-down: moveElement,
Third drop-down: false,
The correct event listener syntax is addEventListener(type, listener, useCapture). The first argument must be " click " because the function must run when a button is pressed. The second argument must be moveElement, not moveElement(), because the event listener expects a function reference. Using parentheses would call the function immediately while the page is loading instead of waiting for the user to press a button. The third argument controls the event phase. false means the listener runs during the bubbling phase, which is the normal behavior for button click handling. true would register the listener for the capturing phase instead.
Since the code uses document.querySelectorAll( " .item " ), it selects all elements with the class item. The for loop then attaches the same click listener to each selected button individually. This ensures that all four buttons invoke moveElement when clicked.
NEW QUESTION # 35
You are creating a script that reads a JSON menu file and displays the Entree, Price, and Description.
Complete the code by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Answer:
Explanation:
Explanation:
First drop-down: var xhr = new XMLHttpRequest();
Second drop-down: if(xhr.status===200){
Third drop-down: responseObject = JSON.parse(xhr.responseText);
The script must first create an XMLHttpRequest object, so the correct first selection is var xhr = new XMLHttpRequest();. This object performs the asynchronous request for menu.json. After the request finishes, the onload callback executes. The response should be processed only when the request succeeds, so the correct status check is if(xhr.status===200){; HTTP status 200 means the file was successfully retrieved.
Status codes 403, 404, and 500 represent forbidden access, missing resource, and server error conditions, so they are not appropriate for normal JSON processing. The JSON file is returned as plain text through xhr.
responseText, so it must be converted into a JavaScript object with JSON.parse(xhr.responseText). Once parsed, the code can access responseObject.menu[i].Entree, Price, and Description inside the loop and build the display output. responseXML is incorrect because the source file is JSON, not XML.
NEW QUESTION # 36
Which JavaScript method is used to draw a circle on a canvas?
Answer: A
Explanation:
The correct method is arc(). In the Canvas 2D API, circles and circular arcs are drawn by creating an arc path on the canvas rendering context. MDN defines CanvasRenderingContext2D.arc() as creating a circular arc centered at (x, y) with a specified radius, start angle, end angle, and drawing direction. To draw a full circle, the common pattern is to call beginPath(), then arc(x, y, radius, 0, 2 * Math.PI), and then use stroke() or fill() to render the path. There is no standard Canvas 2D method named circle(), so option A is invalid. ellipse() can draw ellipses and can mathematically draw a circle if both radii are equal, but the classic and exam-targeted method for drawing a circle is arc(). bezierCurveTo() draws cubic Bezier curves and is used for custom curved paths, not the direct circle primitive. References/topics: Canvas 2D context, arc() method, drawing circles, radians, path rendering.
