What is the process for splitting array values and comparing two separate splits?

To accomplish your goal of comparing two split arrays and obtaining the second parameter of the latest date, you can follow these steps. Firstly, split both given arrays by using the semi-colon separator. Then, obtain the date values by applying the JavaScript Date object on the corresponding string values. Finally, compare the two dates and retrieve the second parameter of the more recent date. Here's some sample code:

const array1 = ["A;35;Jan 20 2023;", "B;45;Feb 20 2013"];
const array2 = ["A;23;Feb 20 2024;", "B;18;Mar 20 2022"];

let latestDateValue = 0;

array1.forEach(item => {
  const splitItem = item.split(";");
  const date = new Date(splitItem[2]);
  if (date > latestDateValue) {
    latestDateValue = date;
  }
});

array2.forEach(item => {
  const splitItem = item.split(";");
  const date = new Date(splitItem[2]);
  if (date > latestDateValue) {
    latestDateValue = date;
  }
});

let latestValueOfLatestDate;

array1.concat(array2).forEach(item => {
  const splitItem = item.split(";");
  const date = new Date(splitItem[2]);
  if (date.getTime() === latestDateValue.getTime()) {
    latestValueOfLatestDate = splitItem[1];
  }
});

console.log(latestValueOfLatestDate);

I hope this solution helps you. Let me know if you have any questions.

To get the value of the latest date and the 2nd parameter (35 value) from the given array, we can follow these steps: 1. Loop through the "Info" array and split each value with ';' to get an array of arrays. 2. Extract the date value from each sub-array using the index of the date string. 3. Convert each date string to a JavaScript Date object using the Date constructor. 4. Find the latest date object from all the extracted dates using the Math.max() and map() methods. 5. Get the index of the sub-array that contains the latest date. 6. Use the index to get the 2nd parameter value (35 value) from that sub-array. Here's an example code snippet that implements the above steps:

const infoArray = ["A;35;Jan 20 2023;", "B;45;Feb 20 2013"];

// Step 1: Convert each array value into an array of values
const splitInfo = infoArray.map(info => info.split(';'));

// Step 2: Extract date value from each sub-array (index 2)
const dates = splitInfo.map(subArr => subArr[2]);

// Step 3: Convert date string to Date object
const dateObjs = dates.map(date => new Date(date));

// Step 4: Find latest date object
const latestDate = new Date(Math.max(...dateObjs));

// Step 5: Get index of the sub-array containing latest date
const latestDateIndex = dateObjs.findIndex(date => date.getTime() === latestDate.getTime());

// Step 6: Get 2nd parameter value from sub-array
const secondParamValue = splitInfo[latestDateIndex][1];

console.log(secondParamValue); // Output: 35

Note: This code assumes that the date follows the format "Month day year", as given in the example. If the date format is different, the code may need to be modified accordingly.
