Lesson 10 Code-Walk-Get-Amounts-In: Mentioning getAmountOut instead of getAmountIn — Mistake?

[EvolOfThings]

In Lesson 10, during the explanation of the first iteration of the for-loop, the instructor mentions that the amount of token out (which we already know) is stored in amounts[n-1], and that the getAmountOut function is used to calculate the token in needed. This occurs at 1:47 in the video.

Was this a misspeak, or do we actually call getAmountOut for the first iteration in this context? I'm a bit confused. Can anyone clarify?

Thanks in advance!

Hello @EvolOfThings, That was a mistake, I believe. He wanted to say getAmountIn. The reason for my conclusion is that just before he said, we need to call the function getAmountOut he said, the amount of tokenOut we already know. So it doesn't make sense to call getAmountOut when we already know the amount of tokenOut so what makes sense is to call getAmountIn to know the amount of tokenIn that we need to get the amount of tokenOut that we already know.

Yeah, thank you for confirming it. I was trying to justify why we would use getAmountOut function there, but it does not really makes sense. It should be getAmountIn function, it was just a slip of the tongue mistake.

Yeah.
