Anyone know any Api or something similar to get the price of an LP in pancakeswap with Js

Of Pancakeswap

getReserves from lp, gettotalsupply, do some division to find token/lp ratio, divide your lp by that number, use pancakeswap api to get price

what's cheaper on gas fees
1. storing a function return as a variable and calling it multiple times
2. calling the function over and over again

2.

any edge cases to that?

You have to be precise how you are going to write it

ah yes, very helpful, thanks.

so far my conclusion from testnet using both internal and external functions is 1

1

That's even true for every programming language based on computation required

There might be some exceptions if the function body is really really small

true, but since i'm pretty new to solidity i can't ever be too sure. it's possible creating a variable in a function costs more gas than i expect

If a single variable costs more than an entire function call, then that's the worst programming language I've ever seen😅
