javascript arrays
This example demonstrates a simple JavaScript function that creates an array of sequential numbers using a for loop. The code defines a `range` function that takes a numeric argument, pushes each incrementing value into an empty array, and returns the result. It then logs the output of `range(4)` to the browser console. The visualization relies solely on native JavaScript array methods and console output, with no external libraries or rendering frameworks involved. The example illustrates basic array construction and iteration logic in a minimal, self-contained HTML page.
