// Value types can be three, value1, value2, value3

const items=[
  {
    "date": "2023-02-01",
    "value1": 1,
    "value2": 1
  },
  {
    "date": "2023-02-03",
    "value1": 1,
    "value2": 1

    "value2": 1

    "value3": 1
  },
  {
    "date": "2023-02-08",
    "value3": 1
  },
]

//Notice the first 3 objects have consecutive dates and same values. 
//I want to be able to display the consecutive dates which have same value type and value amount like this: 2023-02-01-2023-02-03: 2
//The none consectuve dates remain as they are

@abel-masila Check on how you can format it

`let start = 0;
let end = 0;

for (let i = 0; i < items.length; i++) {
if (i > 0 && items[i].value === items[i - 1].value) {
end = i;
} else {
if (end > start) {
console.log(Dates: ${items[start].date} - ${items[end].date}, Value: ${items[start].value});
}
start = i;
end = i;
}
}

if (end > start) {
console.log(Dates: ${items[start].date} - ${items[end].date}, Value: ${items[start].value});
}`
