Just map the tokenIds array:
const newstrings = tokenIds.map(i => strings[i]);

I have the following 2 arrays
tokenIds = [0,1,3]
and
strings = ["hello", "foo", "goodbye", "bar"]
what would be the best way to create a new array with the elements in "strings" array which index's match the values of "tokenIds" array?
Such as creating a new array like the following
newstrings = ["hello", "foo", "bar"]
I have tried the following:
const newstrings = strings.filter(index => tokenIds.includes(tokenIds.index));
Thanks in advance!
