Fill Json with missed Data - json

Question

I have a json and in my example values for years 1996 to 2012 were left out. Is there any way to insert the missing values (years)? If yes, how? Finally, the json should be completely filled in (1988 to 2021) and insert the value "0" for the years where the year is missing.
Kind Regards and thank you

2012 is there. Filling in 1996 - 2011:
'use strict';
const fs = require('fs');
let rawdata = fs.readFileSync('input.json');
let obj = JSON.parse(rawdata);
const len = 16;
const insertPos = 8;
const totSize = 35;
const tempArrData = new Array(len).fill(0);
const tempArrYears = new Array(len);
let i = 0;
for (let y = 1996; y < 2012; y += 1) {
tempArrYears[i] = y + '';
i += 1;
}
const arrV = obj.data.ArrayValue;
arrV.splice(insertPos, 0, ...tempArrData);
const arrY = obj.data.ArrayYears;
arrY.splice(insertPos, 0, ...tempArrYears);
for (let i = 0; i < totSize; i += 1) {
console.log(`${obj.data.ArrayYears[i]} , ${obj.data.ArrayValue[i]}`);
}
Output:
