Answer 1

You can use Set after converting the string elements to uppercase.Here ... is spread operator

var arr = ['verdana', 'Verdana', 2, 4, 2, 8, 7, 3, 6];

var result = arr.map(function(item) {
  return typeof item === "string" ? item.toString().toUpperCase() : item
})

result = [...new Set(result)];

console.log(result);
