uncaught type error

Question

There is an error when i run the code, saying that the length is undefined, what could be the problem?

Answer 1

Post the code related to your question and maybe you will get an answer. Otherwise, it's like you gave us a dart, put a blindfold on us, spun us in a circle, and then asked us to through a bullseye!

Answer 2

You're trying to access the 'length' (variable or property) for doing something with it, but that cannot be done because either the 'length' variable hadn't been declared and/or assigned with a value, or the property doesn't exist (or is undefined: good object reference but wrong value stored, or wrong reference object for the 'length' property) ^^

That cannot be possible to be more accurate if you don't share your code ;P (save a code playground project with your code if not still done, click on share button -- top right three dot linked by two lines icon -- and copy paste the link here)...
