Looping over nested structures
You've seen how you can loop over a vector to return the values within that vector. One step further than this is to loop over a vector of vectors, returning the corresponding values in order. This can be referred to as a 'nested' structure, where one vector is inside another vector. You'll often find nested structures in practice, so understanding how to iterate over these structures and extract data from them is an important skill to have.
In this example, we have changed our previous stock_tickers vector to include the current stock price of each ticker, and we have renamed the vector to stocks. Note the structure of the nested vector below.
4-element Vector{Vector{Any}}:
["AAPL", 151]
["AMZN", 94]
["GOOG", 97]
["MSFT", 241]
