JavaScript Hello World: Here's What You Need To Know Lesson - 2Īll You Need to Know About JavaScript Arrays Lesson - 3 My code is below.An Introduction to JavaScript: Here Is All You Need to Know Lesson - 1 This code compiles and runs OK, but when I click on the buttons (for 15%, 18%, 20%, and 22%) it doesn't seem to run the calculations - the tip and total amounts show up as 0.00 and the eachperson (what each person pays if you split the bill) shows up as NaN (Not a number.) The code is simple enough, so this is probably a simple error.but I don't know where it is and neither does the teacher.
