Discussion:
in step 99 of the decimal to binary project (js beta), the instructions are: Set the value of the msg property to the following string: Example Code "decimalToBinary(1) returns '1' (base case) and gives that value to the stack below. Then it pops off the stack." Note that, since the string itself contains double quotation marks, you'll need to escape them with a backslash, or use single quotation marks for your string value. The remarks at the end say we need to escape the 'double quotation marks' in the string, but the string doesn't have any double quotation marks and I'm able to copy the string as-is and submit it with success to move onto step 100. However, in step 100, the string suddenly changes in the code and becomes: 'decimalToBinary(1) returns "1" (base case) and gives that value to the stack below. Then it pops off the stack.' And now we can see the double quotes that step 99 was referring to. I'm not sure what happened between step 99 and 100 but I think it is confusing and some fix (to one or the other of these steps) is needed. The above is what I have in the editor in step 99 when I click submit and successfully move forward to step 100. N/A No response N/A No response
As I can see, in the step 99, it shows how to use single quotation marks instead of double so that the string works. And in the 100th step it makes a swap in the use of single and double quotation marks. Is there a need to make the swap in the quotation marks in step 99? As the note would then become useless and would need to be changed also
How do you explain the note? I didn’t see double quotation marks in the string that need a backlash , did you?
All I can infer from the note is that to emphasize that 1 by either "1" or '1' a backlash is required or the need to change the quotation so that it does't count that string as ending at that point. The message has chosen the latter solution.
That is not how you should interpret the note. It clearly uses present tense when it says “the string itself contains quotation marks”. This is undeniable and needs an appropriate fix.

But it's indirectly stating to use whichever method to print the required message right? Possibility1: "decimalToBinary(1) returns '1' (base case) and gives that value to the stack below. Then it pops off the stack." Possibility2: "decimalToBinary(1) returns "1 " (base case) and gives that value to the stack below. Then it pops off the stack." I just made the msg same as step 100
And for that double quotation mark, the note says as the string starts with ", it should end with ", and thus it can't use simply " for "1" and need to use '1' instead. Backlash would be another method to amend this issue as I stated in the message above.
Specifying why it's bad would be a little helpful rather than thumbs down, no?
It's a bit odd that step 100 uses single quotes for the string, while other strings in the file use double quotes instead. To simplify things, I think we could: Remove the note from step 99 Swap the quotation marks of the string from step 100 onward: -
thanks. Incorporated both of your suggestions in the linked PR.
