This example presents five JavaScript practice problems focused on manipulating objects and arrays, with output intended for the browser’s developer console rather than SVG or other visual rendering. The code demonstrates basic data operations such as merging object properties by matching names, finding common elements between arrays using nested loops and the `includes` method, sorting an array of state objects by population, and using a loop with the modulus operator to filter numbers. It relies on vanilla JavaScript for most tasks and uses the D3 v4 library’s `d3.range` function to generate a sequence of integers from 1 to 10.

Sample problems: objects and arrays

This example presents five JavaScript practice problems that manipulate arrays and objects, with output visible only in the developer console. The problems demonstrate tasks such as merging object properties between arrays, finding common items, sorting objects by a numeric property, and filtering numbers using the modulus operator. The code uses D3 v4’s `d3.range` to generate an array of integers, while array methods like `forEach` and `sort` handle the core logic. No SVG or visual rendering is involved, as the focus is purely on algorithmic thinking with plain data structures.

Sample problems: objects and arrays

This example presents five JavaScript practice problems embedded in an HTML page, focusing on array and object manipulation rather than visual output. The exercises involve merging state names with their two-letter IDs, finding common elements between arrays, sorting state objects by population, and using the modulus operator to filter numbers. Built with D3 v4, the code uses `d3.range` to generate a sequence of integers, though all results are meant to be viewed in the browser’s developer console, as no SVG or graphical rendering is included.

Sample problems 2: objects and arrays

This example presents four JavaScript practice problems that operate on arrays and objects, demonstrating data filtering, comparison, and sorting without any visual rendering. The code uses plain JavaScript methods such as `forEach`, `includes`, and `sort` to manipulate datasets like state objects with names, locations, and populations, and arrays of characters and numbers. It logs results to the browser’s developer console, including filtering states by location substrings, finding items unique to one array, sorting states alphabetically, and identifying even population values. The visualization relies entirely on the console output rather than D3 or SVG, though it is built within a D3 v4 environment.

Sample problems 3: objects and arrays

This example presents four JavaScript practice problems for manipulating arrays of objects, using U.S. state population data. The page shows a static text heading but the core activity occurs in the developer console, where the user observes output. The code demonstrates computing an average both with the D3.js `d3.mean()` function and manually using `forEach` and `while` loops. The dataset is an in-code array of state objects containing name, ID, and population fields, with no SVG or visual rendering involved.

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.

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 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.
