A Class of Parallel Arrays Manipulation

const {Same} = require("Same");
var same = new Same();

async function main() {
    let ar1 = [0, 1, 2, 3];                 // creates a 4-indexed array
    let ar2 = ["zero", "one", "two"];       // creates a 3-indexed array
    same.insert(ar1, ar2);                  // inserts the arrays in the Same; since ar2 has one value less than ar1, in the second array there will be an empty space
    await same.replaceUnd(["three"])        // the empty space is overwritten with the string "three"
    console.log(same);
}

main()                                      // calls the async function (THE MODULE replaceUnd() MUST BE AWAITED)
