JavaScript - Get the value of a variable generated inside a forEach loop

Question

I would like to get the value of a variable generated inside a forEach loop outside of it, please look at the code snippet:

  var variable = "";

  array.forEach(el=>{
  variable =  el.checkStatus;
  })

  //How to get the value of variable here ?

Answer 1

  var statuses = array.map(el => {
    return el.checkStatus;
  })

Then simply call statuses[index] depending on the status you want

Answer 2

You could make variable an array of each elements checkStatus values.

var variable = new Array();

array.forEach(el => {
    variable.push(el.checkStatus());
})

This would be more elegantly done using an array map function though.

var variable = array.map(el => el.checkStatus())
