+### JSONtoCSV
+
+Converts an array of objects to a comma-separated values (CSV) string that contains only the `columns` specified.
+
+Use `Array.join(demiliter)` to combine all the names in `columns` to create the first row.
+Use `Array.map()` and `Array.reduce()` to create a row for each object, substituting non-existent values with empty strings and only mapping values in `columns`.
+Use `Array.join('\n')` to combine all rows into a string.
+Omit the third argument, `delimiter`, to use a default delimiter of `,`.
+
+```js
+const JSONtoCSV = (arr, columns, delimiter = ',') =>
+  [
+    columns.join(delimiter),
+    ...arr.map(obj =>
+      columns.reduce(
+        (acc, key) => `${acc}${!acc.length ? '' : delimiter}"${!obj[key] ? '' : obj[key]}"`,
+        ''
+      )
+    )
+  ].join('\n');
+```
+
+```js
+JSONtoCSV([{ a: 1, b: 2 }, { a: 3, b: 4, c: 5 }, { a: 6 }, { b: 7 }], ['a', 'b']); // 'a,b\n"1","2"\n"3","4"\n"6",""\n"","7"'
