"Exploring the world of coding with pattern numbers and loops in

I am attempting to use JavaScript code to generate a specific pattern.

To do this, I would like the user to input the following parameters:

For instance, the starting number: 2 Insert the final number: 5 Enter the jump: 2

So far I have tried the following method:

let startNumber = Number(prompt("Enter a starting number:"));
let endNumber = Number(prompt("Enter an ending number:"));
let jump = Number(prompt("Enter a jump value:"));
let output = "";
let count = startNumber;

for (let i = 1; i <=endNumber; i++) {

    for (let j = 1; j <= i; j++) {
       output += count +",";

        count++;
    }
    output += "\n";
}
console.log(output);

>2
>3,4,5,
>6,7,8,9,10,
>11,12,13,14,15,16,17,
>18,19,20,21,22,23,24,25,26

Displayed result will be like above example

UPDATE

After further review, it appears that my initial interpretation of the requirement was incorrect. The task is to display all numbers between a specified start and end point, with each line containing a maximum of 1 + 2*(n-1) numbers.

// To accommodate the non-standard node.js prompt, hardcoded values have been used
let beginNumber = 2;
let endNumber = 26;
let increment = 2;

let currentNum = beginNumber;
let currentLineSize = 1;
let currentLine = [];
let resultOutput = "";

while(currentNum <= endNumber) {
    currentLine.push(currentNum);
    if (currentLine.length === currentLineSize || currentNum === endNumber) {
        if (resultOutput) {
            resultOutput += '\n'; 
        }
        resultOutput += currentLine.join(',');
        currentLine = [];
        currentLineSize += increment;
    }
    currentNum++;
}

console.log(resultOutput);

Initial answer

Based on my understanding, you require user input for a starting number, an ending number, and a step size for generating a list of numbers. Subsequently, you want to display these numbers separated by commas.

Here's one approach to achieve this:

let beginNumber = Number(prompt("Enter a starting number:"));
let endNumber = Number(prompt("Enter an ending number:"));
let increment = Number(prompt("Enter a step size:"));
let outputString = "";
const numList = [];
let currentNum = beginNumber;

while(currentNum <= endNumber) {
  numList.push(currentNum); 
  currentNum += increment; 
}
if (currentNum - increment < endNumber) {
  numList.push(endNumber); 
}
const finalResult = numList.join(',');
console.log(finalResult);
