Creating a collection of time elements

Question

Creating a collection of time elements

My current array consists of various time values, such as:

//     '6:00pm',
//     '7:00pm',
//     '8:00pm',
//     '9:00pm',
//     '10:00pm',
//     '11:00pm',
//     '12:00am',
//     '1:00am',
//     '2:00am',
//     '3:00am',
//     '4:00am',
//     '5:00am',
//     '6:00am',
//     '7:00am',
//     '8:00am',
//     '9:00am',
//     '10:00am',
//     '11:00am',
//     '12:00pm',
//     '1:00pm',
//     '2:00pm',
//     '3:00pm',
//     '4:00pm',
//     '5:00pm',

I am looking to format these times into objects like the example below:

[
    {
      time: "6:00",
      Meridiem: "pm"
   },
   {
      time: "7:00",
      Meridiem: "pm"
   }
]

However, I am facing a roadblock when trying to loop through the times and need assistance. My attempted solution so far includes:

const array = new Array(12);
let timeArray = [];
for(var i=1;i<=array.length;i++){
    let x = {
        time: i,
        meridium: "AM"
    }
    timeArray.push(x);
};

console.log(timeArray, 'timeArray')

I am aware that this is not correct. Could someone provide guidance on how to achieve the desired output?

If you're looking to dynamically create an array in your code, one approach is to utilize the Array constructor along with the fill method to populate it, and then map the indices to their corresponding time values. To compute the time, you can use the modulo operator (%) to handle cases where the index % 12 results in 0, which should be replaced with 12.

To generate a 24-hour array starting at 6 PM, you can first create a complete 24-hour array, split it at the 6 PM mark (index 18), and concatenate the two halves back together using methods like slice and spread syntax depending on your specific requirements.

let times = Array(24).fill().map((_, i) => ({
  time: `${i % 12 || 12}:00`,
  Meridiem: i < 12 ? "am" : "pm"
}));

times = [...times.slice(18), ...times.slice(0, 18)];

console.log(times);

For transforming each item in your array, consider using the Array.map method.

var arr = ['1:00pm',
    '2:00pm',
    '3:00pm',
    '4:00pm',
    '5:00pm',];
var newArr = arr.map(item =>{
  return {
    time: item.substring(0, item.length - 2),
    meridium : item.substring(item.length - 2),
  }
})

console.log(newArr)

If you want to format a time array, you can utilize the map function along with the slice method as shown in the code snippet below.

const listOfTime = ['6:00pm','7:00pm','8:00pm','9:00pm','10:00pm','11:00pm','12:00am','1:00am','2:00am','3:00am','4:00am','5:00am','6:00am','7:00am','8:00am','9:00am','10:00am','11:00am','12:00pm','1:00pm','2:00pm','3:00pm','4:00pm','5:00pm'];

var formattedTime = listOfTime.map(function(val,index) {
  return {hour: val.slice(-2,listOfTime[index].length), meridiem: val.slice(0,listOfTime[index].length-2)};
})

console.log(formattedTime);

  return {hour: val.slice(-2,listOfTime[index].length), meridiem: val.slice(0,listOfTime[index].length-2)};
})

console.log(formattedTime);

To format time values, you can either use the slice method or substring

const ArrOfTimeValues = ['6:00pm','7:00pm','8:00pm','9:00pm'];

const FormattedArr = [];
const ArrLength = ArrOfTimeValues.length;
for(let i = 0;i<ArrLength;i++){
  let ItemLength = ArrOfTimeValues[i].length;
  let Meridiem = ArrOfTimeValues[i].slice(-2,ItemLength);
  let TimePoints = ArrOfTimeValues[i].slice(0,ItemLength-2);
  let NewItem = {
    time:TimePoints,
    Meridiem:Meridiem
  }
  FormattedArr.push(NewItem);
}
console.log(FormattedArr);
