How can i get an index of an Array in an Array of a Json Doc

Question

I have a Json Doc which i get from my back end which looks like the one below. It has an emails Array which the doc under it has and email array. I need to get the index the email array is part of which has a match for an email address so i can update the doc. i used lodash before to search for a key in a array of docs before with _.find and _.indexOf but not sure how this would work in an Array of Array case.

{
  "_type": "email_campaign",

You could use findIndex and includes:

const index = docs.emails.findIndex(item => item.email.includes('[email protected]'))

try this:

emailToFind="xxxxxxxxx"
var indexes=[]
var test= res.emails.map((el1,i1)=>{
  el.email.map((el2,i2)=>{
    if (el2===emailToFind){
      indexes.push(i1)
    }
  })
})
