Answer 1

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

function getUniqueValuesWithCase(arr, caseSensitive){
    let temp = [];
    return [...new Set(caseSensitive ? arr : arr.filter(x => {
        let _x = typeof x === 'string' ? x.toLowerCase() : x;
        if(temp.indexOf(_x) === -1){
            temp.push(_x)
            return x;
        }
    }))];
}
getUniqueValuesWithCase(arr, false); // ["verdana", 2, 4, 8, 7, 3, 6]
getUniqueValuesWithCase(arr, true);  // ["verdana", "Verdana", 2, 4, 8, 7, 3, 6]
