JavaScript arrayToList

Question

can anyone help me figure what i did wrong in my code? Cause I wanna created a function which can help me turn all the array data into list and print the list out.

Answer 1

You may try this as well :

    
    
    function arrayToList(arrayx){ 
    for(var i = arrayx[0];i < Math.max.apply(Math,arrayx); i+=arrayx[0])
    {
     var list = {
     value: i,
     rest: {
     value: i+=10,
     rest: null
       }
      }
    return list;
    }
    }
    
    console.log(arrayToList([10 , 20]));

Answer 2

    // This is a function to make a list from an array
    // This is a recursive function
    function arrayToList(array) {
        // I use an object constructor notation here
        var list = new Object();
        // This is to end the recursion, if array.length == 1, the function won't call itself and instead
        // Just give rest = null
        if (array.length == 1) {
            list.value = array[array.length - 1];
            list.rest = null;
            return list;
        } else {
            // This is to continue the recursion.  If the array.length is not == 1, make the rest key to call arrayToList function
            list.value = array[0];
            // To avoid repetition, splice the array to make it smaller
            array.splice(0,1);
            list.rest = arrayToList(array);
            return list;
        }
    }
    
    
console.log(arrayToList([10, 20]));
