JavaScript JavaScript Array Iteration Methods Combining Array Methods Nested Data and Additional Exploration

He said, "call reduce() method on the array" and the syntax is '.array()'

I was just thrown off. The teacher had just said and talked about using the .reduce method on the array of arrays but had proceeded to type .array() and talking as if .array is .reduce. Is it? What is going on . . . What is this new syntax ?

It's an error, not a new method. He meant to type "reduce" and he fixes it at about 2:48 in the video.

I've seen this happen in a few videos. Instead of editing them out, I think they might deliberately leave teacher errors (along with the corrections) in the videos sometimes as a demonstration of how to identify and correct such issues when you encounter them yourself. Well, that and perhaps as proof that the teachers are not robots. :laughing:

While I do agree with showing the authenticity it throws me off when they do that because this syntax is already so tricky to learn. I need it perfect hahaha
