   3: "text3"
1: Array
   0: "2"
   1: "text1"
   2: "text2"
   3: "text3"

You want to map the user input to the index of inner arrays or to the values at oth position of each inner array? — shantanu kaushik

    let yourObj = {0:{ 
       0: "1",
       1: "text1",
       2: "text2",
       3: "text3"},
    1: {
       0: "2",
       1: "text1",
       2: "text2",
       3: "text3"},
    2: {
       0: "3",
       1: "text1",
       2: "text2",
       3: "text3"}
    },
    input = [3,2,1];

    let sortArr = (input) => {
    
    let obj = {};
    
    for(let i = 0; i< input.length; i++){
    obj[i] = yourObj[--input[i]];
    
    }
    return obj;
    }

     console.log(sortArr(input))   //Call sort array here

let arr = [ ["1","text1","text2","text3"],["2","text1","text2","text3"],["3","text1","text2","text3"]]
const newOrder = [3,2,1];

let result = newOrder.map(idx => arr.find(el => el[0] == idx))

console.log(result)
