JavaScript Function to Display CSV Data with Toggleable Transparency

The code is a JavaScript function called "displayCSV" that takes in a "data" parameter. \n\nInside the function, it destructures the "column_type" and "data" properties from the "data" parameter.\n\nIt then retrieves an element with the id "textDisplayArea" using "document.getElementById" and assigns it to the "textDisplayArea" variable.\n\nNext, it clears the content of the "textDisplayArea" by setting its "innerHTML" to an empty string.\n\nThe function then iterates over each row in the "csvData" array using "forEach" and creates a "

" element for each row.\n\nInside the row iteration, it also iterates over each column in the row using "forEach" and creates a "" element for each column.\n\nThe text content of each "" element is set to the corresponding column value.\n\nIf the "column_type" is "odd" and the column index is odd, or if the "column_type" is "even" and the column index is even, the "" element is given a class of "transparent". \n\nAdditionally, an event listener is added to each "" element. When the "" element is clicked, the "transparent" class is removed. After a delay of 12 seconds, the "transparent" class is added back to the "" element.\n\nFinally, the "" element is appended to the "

" element, and the "

" element is appended to the "textDisplayArea" element.\n\nThis function is used to display CSV data in a HTML element with the id "textDisplayArea". The transparency of certain columns can be toggled by clicking on them.
