問題 #46
Which value does the following JavaScript code fragment store in the variable num?
var num = localStorage.length;
答案：B
解題說明：
The value stored in num is the number of key-value pairs currently stored in localStorage. The localStorage object implements the Web Storage Storage interface, which stores data as named string key/value entries for the current origin. Its length property is read-only and returns the number of data items stored in that Storage object, not the size of the stored data and not the remaining capacity. MDN's Storage reference explicitly defines length as returning the number of data items stored, and its example shows that after three items are added to localStorage, localStorage.length returns 3. Therefore, if the storage area contains five named entries, num receives 5; if it contains no entries, num receives 0. Option A is incorrect because available bytes are not exposed through length. Option B is unrelated to Web Storage. Option C is incorrect because browser storage quota or capacity is separate from the length property.

問題 #47
Match each stage of Application Lifecycle Management to the task that occurs during that stage.
Move each stage from the list on the left to the correct task on the right.
Note: You will receive partial credit for each correct match.
答案：
解題說明：
Explanation:
Application Lifecycle Management organizes website creation into ordered stages that move from intent to implementation and long-term support. The Plan stage comes first because it establishes why the website exists, who the audience is, and what goals the application must satisfy. The Design stage converts those requirements into structure, including page layout, navigation, interface organization, and visual arrangement.
The Develop stage is where the website is built by writing HTML markup, CSS styling, JavaScript behavior, and integrating required assets or APIs. The Test stage evaluates whether the completed website functions correctly and is usable according to requirements; this includes checking features, layout behavior, validation, and user workflows. The Deploy stage publishes the finished website to the target hosting or production environment so users can access it. Finally, the Maintain stage occurs after release and includes monitoring, updating, fixing defects, improving compatibility, and keeping content or functionality current. References

問題 #48
You need to define a grid that meets the following requirements:
* Explicitly sets the width of 6 equal columns of 1 fraction
* Explicitly sets 5 varied sized rows
* Defines 15px of space between each grid column
* Defines 10px between each grid row
Complete the code by selecting the correct option from each drop-down list.
答案：
解題說明：
Explanation:
display: grid;
grid-template-columns: repeat(6, 1fr);
grid-template-rows: 50px 50px 150px 150px 100px;
grid-gap: 10px 15px;
The correct grid definition starts with display: grid;, which turns the element into a CSS Grid container. To explicitly create six equal-width columns, the correct property is grid-template-columns, and the most efficient value is repeat(6, 1fr). The repeat() function avoids writing 1fr six separate times, while 1fr assigns each column one equal fraction of the available grid width. The five row sizes must be explicitly declared with grid-template-rows, using the exact varied values shown: 50px 50px 150px 150px 100px. This creates five rows with fixed pixel heights. For the spacing requirement, grid-gap: 10px 15px; is the correct shorthand.
The first value controls the row gap, so rows are separated by 10px; the second value controls the column gap, so columns are separated by 15px. References/topics: CSS Grid containers, explicit grid tracks, grid-template- columns, grid-template-rows, repeat(), fractional units, grid gaps.
問題 #49
Which JavaScript method is used to draw a circle on a canvas?
答案：C
解題說明：
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.
問題 #50
You write the following JavaScript code. Line numbers are included for reference only.
01 < script >
02
03 beststudent = new Student( " David " , " Hamilton " );
04 document.write(beststudent.fullname + " is registered. " );
05 < /script >
You need to write a function that will initialize and encapsulate the member variable fullname.
Which code fragment could you insert at line 02 to achieve this goal?
Note: Each correct answer presents a complete solution.
答案：B
解題說明：
The correct answer is A because the code at line 03 creates an object by calling a constructor function with the new keyword. A constructor function must be declared with the same identifier used in the new Student( " David " , " Hamilton " ) expression. Inside the constructor, instance members should be assigned through this, because this refers to the newly created object. Option A correctly initializes this.firstname, this.lastname, and this.fullname, so beststudent.fullname is available at line 04 and evaluates to " David Hamilton " . Option B is invalid JavaScript syntax because var student(firstName, lastName) is not a valid function declaration. Option C is also invalid syntax for the same reason: var Student(firstname, lastname) cannot declare a constructor.
Option D uses a valid function declaration, but it assigns firstname, lastname, and fullname without this, which creates or references non-encapsulated variables rather than properties of the constructed object.
References/topics: JavaScript constructor functions, new keyword, object instance properties, this, custom classes.
