Should I just take 0th element?

Almost all functions return arrays to enable further manipulation. Lets say you want a signal line of the RSI, you just take the output of the function and enter it in a moving average with a length.

rsi = await ta.rsi(rsi_data, rsi_length);
signal = await ta.sma(rsi, ma_length);

To retrieve the latest value get the last array element.
