Task 130

Debum9

For this task, do I have to print the numbers 0 to 99 as strings. If so, kindly suggest me how I can solve it.

Coderslang_Master

This is the difference between the number and a string

const a = 1;
const b = '1';

a is a number and b is a string.

However, I'm not sure that in this task you're required to convert the numbers into strings.

Just print the number from 0 to 99 into the console using a loop.

If there any issues, add the submission results and your code.

Hello, when I press "Submit task" I get all "Details" wrong, but when I press "Run your code" the results show that at least objectives 1. and 2. are accomplished. Here are my files/code:

helper.js

export let i = 0;
export const myLoop = (m) => {
  while (m < 100) {
    console.log(m);
    m++;
  }
};

solution.js

import { myLoop, i } from './helper.js';
myLoop(i);

@alxjspalma there's no reason to put i outside of the function. It should be encapsulated in it.

You're not the first who makes such a mistake. I'll add it as a hint to the task description.

Coderslang_Master Won't i become 0 in each iteration, if it goes inside de while loop?

This time, I only re-arranged the helper.js file with minimal changes. I put the i inside the function and was able to submit it successfully.

export const myLoop = () => {
    let i = 0;
    while (i <= 99) {
      console.log(i);
      i++;
    }
};

I think the reason people are placing i outside the while loop is because that's how you demonstrate it in the tutorial.
This is a difficult one to solve as the error doesn't make it at all obvious that this is what the automatic test is looking for!

Coderslang_Master

I made a mistake and meant to say "no reason to put i outside of the function".

You're right and it should stay outside of the loop.

Coderslang_Master But it still doesn't want to pass 2 of 3 checks.
✅ 1. myLoop function should print 100 strings
❌ 2. myLoop function should print numbers from 0 to 99
❌ 3. myLoop function should use a while loop

I used typeof i. All of them are numbers.

// helpers.js
let i = 0;

export const myLoop = () => {
  while (i <= 99) {
    console.log(i);
    i++;
  }
};

// solutions.js
import { myLoop } from './helper.js';

myLoop();

Coderslang_Master

The issue is that i was declared outside of the loop.

I'll make amends to the task condition.

Coderslang_Master

Hacktinium Makes sense, though it must be placed outside of the loop, but not outside of the function.

Hi, I just took this lesson today and noticed this mistake. In the lesson, the variable was declared outside the function.

Coderslang_Master

sheila I just checked the lecture and I don't see any evidence of the error. Could you post a screenshot to highlight the issue?

let i = 0;

while (i < 99) {
console.log(i = String(i));
i++;
}
export const myLoop = () => {
console.log(i = String(i));
};

i still received error message

❌ 1. myLoop function should print 100 strings
❌ 2. myLoop function should print numbers from 0 to 99
❌ 3. myLoop function should use a while loop

Coderslang_Master

jomer the function myLoop doesn't print 100 strings to the screen because the while loop is located outside of the function.
