JavaScript: get a range of numbers from one to another.

In JavaScript I needed to create a range of numbers from one number to another. Here is how:

Example:

In this example, I will create a function called range that takes two arguments, start and end, and returns an array of numbers from the start number to the end number (inclusive). The code will include detailed comments to explain each step.

// This function takes two arguments, 'start' and 'end'.
// It returns an array of numbers from 'start' to 'end' (inclusive).
function range(start, end) {
  // Initialize an empty array to store the range of numbers.
  let result = [];

  // Use a for loop to iterate through the numbers from 'start' to 'end'.
  for (let i = start; i <= end; i++) {
    // Add the current number (i) to the 'result' array.
    result.push(i);
  }

  // Return the 'result' array containing the range of numbers.
  return result;
}

// Example usage:
// The function call range(1, 5) will return [1, 2, 3, 4, 5].
console.log(range(1, 5));

This code defines a range function that creates an array of numbers from the start value to the end value. The for loop iterates through the numbers, and the result.push(i) line adds each number to the array. Finally, the function returns the array of numbers.
