I Just Wrote My First JS Function ;D by Stephen0mozzy: 9:00pm On Dec 30, 2022 
function numBtw(first, second, third) {
          if (typeof first != 'number') alert('Sorry, only numbers are allowed');
              if (typeof second != 'number') alert('Sorry, only numbers are allowed');
              if (typeof third != 'number') alert('Sorry, only numbers are allowed');
              for (let i = first; i<=second; i+=third) {
        console.log(i);
    } 
}

numBtw(2, 98, 74);



Basically, the function receives a number within given range (i.e from first (argument) to second (argument) and the third argument is the rate at which the values should change (I nor know the math word for it). (Would currently only work in the console sha). It also kinnda guards against entering non-number values.

I norva sabi HTML DOM just yet, i'd have built it into a small web project

Normalize using double "!==" or
3ple "===" when comparing.

Thank you Chief. I will keep that in mind going forward

Did it work because I did see your conditional statement returning anything here

Yes Boss it works, provided the arguments provided to the function are numbers, then it won't trigger the actions in the conditions. In my example, all three entries 


  numBtw(thisIsANumber, thisIsANumber, thisIsANumber);

What happens if the first parameter is greater than the second parameter.

Are you trying to sum up the first and second parameter to be displayed as third parameter.

Or you want to sum the 3 parameters.

Your conditions may not pass some other test.

Try to use the or "||" operator instead of typing 3 if statement, it'll shorten your code to one if statement. It's a better and cleaner way you can write this code.
