Is there a way in p5js to traverse elements inside an array that is inside another array?

This is the CSV file I am using, and I want to access the elements inside the ingredients column one by one. Since each row has a list of its own how do I access the elements one by one in that list?

From the PoV of a CSV file each column’s element is a single string object.  
However you can turn a string into a string array by using **split()** or [**splitTokens()**](https://p5js.org/reference/#/p5/splitTokens):  
`const ingredients = splitTokens(ingredientsColumn, ', ');`
