(Javascript) Write a function that accepts an array. The function adds its value with the value of the character before to it to generate a number. It returns a string of numbers.

Answer 1

function subtracts(lst){
    result = "";
    var k1, k2;
    for(var i = 0;i<lst.length-1;i++){
        if(typeof lst[i] == "string"){
            k1 = lst[i].charCodeAt();
        }
        else{
            k1 = lst[i];
        }
        if(typeof lst[i+1] == "string"){
            k2 = lst[i+1].charCodeAt();
        }
        else{
            k2 = lst[i+1];
        }
        ch = String.fromCharCode(Math.abs(k1+k2));
        if(i == 0){

            result = result + ch;
        }
        else{
            result = result + ","+ ch;
        }
    }
    return result;
}
