Delete elements with identical values from array "a" and then delete the element at the same index in array "b" as the one removed from array "a"

Question

Delete elements with identical values from array "a" and then delete the element at the same index in array "b" as the one removed from array "a"

Currently, I am facing an issue while plotting a temperature chart as I have two arrays:

a, which consists of registered temperature values throughout the day. For example:

a=[22.1, 23.4, 21.7,...];

and b, containing the corresponding timestamps for each temperature value. For instance:

b= ["2016-12-15 16:50","2016-12-15 16:55","2016-12-15 17:00",...]

These two arrays are interconnected! If I pick the temperature value from

a[2],

it correlates to the timestamp in

b[2]

Here's what I aim to achieve:

I want to "merge" similar values. For instance, if my array a contains values like 22.1 at index 3, 4, 5, 6, and 7, I wish to combine them into one single 22.1 at index 3 of array a. Subsequently, I aim to eliminate all items from array b that correspond to indexes 4, 5, 6, and 7. Furthermore, I want to maintain the order within both array a and array b. Please note that this is just an example, and my actual intention is not always to remove elements indexed from 4 to 7.

It seems like the question is a bit difficult to grasp. However, one approach could be to create an array of objects based on arrays A and B. Each object would contain a time property and a temperature value, structured as follows:

var a = [22.1, 23.4, 21.7 ,22.1];
var b= ["2016-12-15 16:50","2016-12-15 16:55","2016-12-15 17:00", "2016-12-15 17:05"];
var temperatures = a.map((x,i) => ({"values": x, "time": b[i]}));
console.log(temperatures);
