Question 1

Which of the following situations makes D3.js useful?

Accepted Answer

Viewing huge data reports of account detail, e-commerce budgeting, population

Answer

D3.js (Data-Driven Documents) is a powerful JavaScript library specifically designed for creating highly customized and interactive data visualizations for the web. It excels at binding data to DOM elements and transforming them. Therefore, D3.js is particularly useful for presenting and exploring large, complex datasets, such as detailed financial reports, e-commerce analytics, or demographic information, in a visually engaging and understandable manner.

Question 2

How many different kinds of directives are there in vue.js

Accepted Answer

4

Answer

In Vue.js, there are primarily four main categories of built-in directives that provide special reactive behavior to the DOM. These include directives for content rendering (e.g., `v-text`, `v-html`), attribute binding (e.g., `v-bind`), event handling (e.g., `v-on`), and structural directives for conditional rendering and list rendering (e.g., `v-if`, `v-for`). These directives are fundamental for declarative manipulation of the DOM based on data changes.

Question 3

Long-winded documentation is produced in agile development.

Accepted Answer

FALSE

Answer

Agile development methodologies prioritize 'working software over comprehensive documentation,' as articulated in the Agile Manifesto. The focus is on delivering functional increments frequently and gathering continuous feedback, rather than spending extensive time on detailed, upfront documentation. While some documentation is necessary, it is typically concise, just-in-time, and sufficient to support the team's work, avoiding 'long-winded' or excessive paperwork.

Question 4

Arrange the following scrum practices according to the order in which they are carried out.
1. Sprint planning
2. Daily scrum meet
3. Sprint retrospective meet
4. Sprint review meet
5. Sprint

Accepted Answer

1, 5, 2, 4, 3

Answer

The Scrum framework follows a specific sequence of events within each sprint cycle. It begins with Sprint Planning (1), followed by the execution of the Sprint itself (5), during which Daily Scrum Meets (2) occur. At the end of the sprint, a Sprint Review Meet (4) is held to inspect the increment, and finally, a Sprint Retrospective Meet (3) is conducted to identify improvements for the next sprint.

Question 5

What D3 JS selector techniques are there?

Accepted Answer

All of these

Answer

D3.js utilizes several fundamental selector and manipulation techniques to interact with the Document Object Model (DOM). `select()` and `selectAll()` are used to choose elements, while `append()` is used to add new elements to the selection. Additionally, `html()` is a method used to get or set the inner HTML content of selected elements. All these methods are essential for dynamically creating and updating visualizations based on data.
