Question

I am trying to change CSS properties like this one.

-moz-border-radius

To the JavaScript CSS property like so.

MozBorderRadius
         


        

Answer 1

is also possible use indexOf with recursion for that task.

input some-foo_sd_dsd-weqe
output someFooSdDsdWeqe

but is works slower

MozBorderRadius
test1: 3.535ms

code:

function camelCased (str) {

        function check(symb){

            let idxOf = str.indexOf(symb);
            if (idxOf === -1) {
                return str;
            }

            let letter = str[idxOf+1].toUpperCase();
            str = str.replace(str.substring(idxOf+1,idxOf+2), '');
            str = str.split(symb).join(idxOf !== -1 ? letter : '');

            return camelCased(str);
        }       

        return check('_') && check('-');

    }

console.log(camelCased ('-moz-border-radius'));
