How to prepare an array for export to csv?

Question

JavaScript

Hello, in the fiddle https://jsfiddle.net/uqpxykt9/2/ there are 2 functions that work almost correctly, namely they form a csv file with only two lines (line 23 and 25 in the fiddle). Please tell me how to prepare the lines array in the first function so that the second one displays a table with all the lines from the array

Answer 1

return data.map(n => n.join(columnDelimiter)).join(lineDelimiter);
