Practice Problems Matt Klug

This example presents five JavaScript practice problems embedded in an HTML page, with no SVG output—users must open the developer console to see results. It demonstrates array manipulation techniques using plain JavaScript methods like `forEach`, `sort`, and the modulus operator, alongside D3 v4's `d3.range` to generate a sequence of integers. The code combines two arrays by matching object names to add state IDs, logs common elements, sorts state objects by population, and prints values not divisible by three. The page uses the D3 library solely for `d3.range`, with all other logic written in vanilla JavaScript.

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: objects and arrays

This example presents five JavaScript practice problems for manipulating data structures, using the D3 library (v4) within an HTML page. It demonstrates techniques like iterating through arrays with `forEach`, matching objects to copy properties, finding intersecting array elements with `includes`, and sorting an array of state objects by population using the `sort` method and `d3.ascending`. It also shows logging results to the console and using `d3.range` to create a numeric sequence for a modulus-based filtering exercise, though the final solution is left incomplete.

Sample problems

This example presents five JavaScript practice problems focused on array and object manipulation. The code, built with D3 v4, demonstrates iterating through arrays to match objects, finding common elements, sorting an array by population, selecting a single object, and using a modulus operator within a loop. Since the problems do not involve SVG manipulation, users must open the developer console to see the output of each solution. The data are static, embedded within the `index.html` file.

Sample problems: objects and arrays

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.
