I have the following array of arrays (pasted below) and would like to loop through it to count how many times each color appears. What’s the simplest way to go about doing this?
[ ["Brown"], ["Blue", "Green"], ["Red", "Black", "White", "Other"], ["Green"], ["Green", "Gold"], ["Blue"] ];

const data = [ ["Brown"], ["Blue", "Green"], ["Red", "Black", "White", "Other"], ["Green"], ["Green", "Gold"], ["Blue"] ]; const result = data.flat().reduce((a, v) => (a[v] = (a[v] || 0) + 1, a), {}); console.log(result);
