Could someone kindly provide a detailed explanation of this Javascript code, breaking it down step

I'm currently learning Javascript and stumbled upon this code snippet. However, I'm having trouble grasping its functionality. Can someone please break it down for me step by step?

var ar1 = [1, 5, 6, 4, 3, 5, 100, -20];

function funDo(ar) {
    for (k = 0, i = 1, temp = ar.length - 1; k < temp; k++) i = (i <<
        1) + 1;
    for (; i > 0; i--) {
        for (k = 0, sum = 0, temp2 = []; k < ar.length; k++)
            if ((i >> (k)) % 2) {
                sum += ar[k];
                temp2.push(ar[k]);
            }
        if (sum == 10) console.log(temp2);
    }
}
funDo(ar1);

Answer №1

functionFind(array) looks through (a set of integers) array to identify "every series" within array, where the total equals 10 (..and displays them in the console).

Don't hesitate to leave a comment or inquire for additional information. :-)
