How to remove the error values by replacing them?

Question

I have an array with values collected from a sensor. However, once in a while, the sensor returns an error value. I want to replace these values by interpolating them using the closest values in the array. How can I do that easily, considering I can have several error values consecutively?

sensor = [20, 21, 22, 21, 8190, 20, 19, 20, 21, 22, 23, 24, 8190, 8190, 25, 21, 8190]

I want to have this:

sensor = [20, 21, 22, 21, 20.5, 20, 19, 20, 21, 22, 23, 24, 24.5, 24.5, 25, 21, 21]

Answer 1

You can just do something like

const sensor = [20, 21, 22, 21, 8190, 20, 19, 20, 21, 22, 23, 24, 8190, 8190, 25, 21, 8190]

//create a new array and variable

let  arr=[]
let currentNum

//iterate over the old array

sensor.forEach(element =>{ 
  if(element!==8190){
     arr.push(element)
     currentNum=element
  }else{
    currentNum=currentNum+.5

     arr.push(currentNum)
  }
});



console.log(arr)
