Confusion in loops

Question

If I put 'let tableValue' outside a while loop then it shows the same number 10 times and when I write it inside the while loop then it prints a table of the value 'n'.

What is the difference between these two things?

function table(n) {
  let i = 1;
  let tableValue = (n * i);
  while (i <= 10) {
    console.log(tableValue);
    i++;
  }
}
table(9);

function table(n) {
  let i = 1;
  while (i <= 10) {
    let tableValue = (n * i);
    console.log(tableValue);
    i++;
  }
}
table(9);

Answer 1

Use:

function table(n) {
  let i = 1;
  let tableValue = (n * i); // This is 1 * 9, because it is outside the while loop ( the while loop block } don’t worry that it's inside the function, it still needs to be in the while block. I think that’s why you're getting confused.
  while (i <= 10) {
     console.log(tableValue);
     i++;
  }
}
table(9);

I’ve put comments on the line in which I think needs explaining.
