This example presents five JavaScript practice problems embedded in an HTML page, with instructions to view output in the developer console. The code uses d3.v4’s `d3.ascending` method to sort an array of state objects by name, and demonstrates array iteration with `forEach`, string searching with `includes`, and conditional logic to filter states by location or even population values. No SVG or visual rendering is involved; the focus is purely on console-based problem-solving with plain JavaScript arrays and objects.

This example demonstrates five JavaScript practice problems solved with array iteration and sorting methods, with results printed to the browser’s developer console rather than rendered visually. The code uses `forEach`, `search`, `every`, and `sort` to filter states by location, compare arrays, sort state objects alphabetically, and identify even population values. No SVG or D3 visualization is created; the page simply displays instructional text, and D3 v4 is loaded but not utilized in the shown logic.

This example presents two JavaScript practice problems embedded in an HTML page. It shows how to compute the average population of a small array of U.S. states, first using the d3.mean() method and then manually using d3.sum() divided by the array length. The page prints results to the browser’s developer console rather than rendering any visual elements. The code relies on d3.v4 and defines state objects with name, id, and population data inline.

This example presents two JavaScript practice problems embedded in an HTML page with no SVG or visual output. The first problem uses the d3.mean() function from d3.v4 to calculate and log the average population of four U.S. states (Alaska, Virginia, Arizona, Florida) stored in a states array. The second problem asks the viewer to compute the same average without d3.mean(), relying instead on the browser’s developer console to observe results. The code uses the D3.js library for the mean calculation and plain JavaScript for array handling, with no rendering or data visualization involved.

This example presents two JavaScript practice problems embedded in a static HTML page, with no SVG or visual output. It shows a small array of four U.S. states and their populations, then asks the viewer to compute the mean population using the D3 v4 API’s `d3.mean()` method, and again without it. The code prints results to the browser’s developer console, and includes a minimal inline style for full-screen body margins. The data is hardcoded in the script, and the page uses only D3’s core utility function for the first calculation.

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.
