Incorrect value returns

July 19, 2022

I use this function:

function search (){
  v = [[2.0], [3.0], [4.0], [5.0]]
  if(v.indexOf(2.0) != -1){
    Logger.log ('if')
  }else{
    Logger.log('else')
  }
}

editing

My real need is in the values of words like this
I was answered about numbers so I did not change and only added

function search (){
  v = [["One"], ["two"], ["three"], ["four"]]
  if(v.indexOf("One") != -1){
    Logger.log ('if')
  }else{
    Logger.log('else')
  }
}

And instead of "if" returning to me, "else" returns to me.
I apologize for the broken English

>Solution :

You input array is a multi/two dimensional array. You are searching for 2.0 which is actually embedded inside another smaller array. Try changing the function to below.

function search() {
  v = [
    ["One"],
    ["two"],
    ["three"],
    ["four"]
  ]
  if (v.findIndex(e => e[0] === 'One') != -1) {
    console.log('if')
  } else {
    console.log('else')
  }
}

search();
