This example presents four JavaScript practice problems that compute the average population of a small hardcoded array of U.S. states. The visualization shows no graphical output; instead, it demonstrates different programming approaches to calculating a mean. The code first uses the d3.mean() function from d3.v4, then replicates the calculation using a for loop, a forEach method, and a while loop, with results printed to the browser’s developer console. The data source is a literal states array containing names, IDs, and populations for Alaska, Virginia, Arizona, and Florida.

average questions-2

This example presents four JavaScript practice problems embedded in an HTML page, using a small dataset of U.S. states with their populations. The visualization shows no SVG graphics; instead, it prints computed averages to the browser’s developer console. The first problem uses `d3.mean()` from D3 v4 to calculate the mean population, while the second problem computes the same value manually using a `for` loop, a `forEach` method, and a `while` loop as alternative approaches. The code demonstrates basic array iteration and statistical calculation without any visual rendering.

average questions

This example presents four JavaScript practice problems embedded in an HTML page, focused on calculating the average population of a small array of U.S. states. It first uses `d3.mean()` with an accessor function, then demonstrates manual computation via a `for` loop, a `forEach` method, and a while loop. The code outputs results to the browser’s developer console rather than rendering any visualization, making it a purely logic-based exercise using D3 v4’s array utilities and core JavaScript iteration patterns.

Sample problems 3: objects and arrays

This example presents two JavaScript practice problems for computing the mean population of a small array of U.S. states. The code uses D3 v4’s `d3.mean()` for the first solution, then demonstrates two alternative manual approaches—using `forEach` and a `while` loop—to calculate the same average. All results are printed to the browser’s developer console, as the page includes no SVG or visual output. The data is a hardcoded array of state objects containing name, ID, and population values.

Sample problems 3: objects and arrays

This example presents four JavaScript practice problems focused on objects and arrays, using a small dataset of U.S. states with their populations. It shows how to compute the average population both with and without D3’s `d3.mean()` method, demonstrating iterative techniques like `forEach` and `while` loops. The code relies on D3 v4 for the `d3.mean()` call, while the rest uses vanilla JavaScript. No SVG or visual output is generated; instead, results are printed to the browser’s developer console, making the example a code-based exercise rather than a graphical visualization.

Sample problems 3: objects and arrays

This example presents four JavaScript practice problems focused on working with objects and arrays, using a small dataset of U.S. states with their names, abbreviations, and populations. The page displays a title and instructions, but all computation happens in the browser’s developer console. Problem 1 uses `d3.mean()` to calculate and log the average population, while Problem 2 attempts the same calculation manually using `forEach()`, though the code’s logic is flawed. The visualization relies solely on D3 v4 for the mean function, with no SVG or graphical output.

This example presents four JavaScript practice problems that compute the average population of a small dataset of U.S. states. The page displays the problems in a heading and paragraph, while the solutions run in the developer console. The code uses the D3.js v4 `d3.mean()` method for the first problem, then implements the same calculation manually using a `for` loop, `forEach` iteration, and a `while` loop for the remaining three. Each approach prints its result to the console, demonstrating alternative ways to calculate a mean without the D3 helper.

Sample problems 3: objects and arrays

This example presents four JavaScript practice problems centered on arrays of objects, specifically U.S. state data with names, abbreviations, and populations. The visualization itself is minimal—a static HTML page with a heading and instructions—while the actual work happens in the console. The first problem demonstrates using `d3.mean()` with an accessor function to calculate the average population, while the second manually iterates through the array with `forEach` to sum populations and compute the mean. The code relies on the D3 v4 library and includes no SVG manipulation, focusing purely on data processing and console output.

Sample problems 3: objects and arrays

This example presents four JavaScript practice problems embedded in an HTML page, focusing on array and object manipulation with population data for four U.S. states. The first problem uses `d3.mean()` to calculate and log the average population, demonstrating D3 v4’s array statistics method. The second problem attempts the same calculation manually with a `while` loop, but contains an intentional infinite loop and redundant addition. No SVG or visual output is rendered; results appear only in the browser’s developer console. The code relies on the D3 v4 library’s `mean()` function and standard JavaScript array traversal.
