In the student overview section, there is no mention of the use of === for Javascript. Since the app is using Javascript, students were confused by the warning they were getting if they didn’t use === in the if statement to compare values.


@jmclean What bubble are students getting that warning for? It really isn’t addressed until stage 8 in this unit, and even then just briefly… see below.

Also, check out this thread about the difference.

I didn’t remember seeing this when I did 5.5 with my students, but I could have missed it - can you give the bubble number so I can look into it a bit more?



Actually, it looked like it only gave a warning when students were trying to test whether the variable was equal to 0.
