I need to loop through thus array:

const arr =  [1,2,3]

...and to store the data from the array in this way:

const test =  = dataIndex.forEach((i, n) => {return(i)})

When i will use test, i want to have next data in it:

1
2
3

Now my code looks like that:

const arr = [1,2,3]
const test = arr.forEach(i => i)
console.log(test) //i get undefined

In this code i get undefined. How to achive what i want?

use `array.map` – Pranav C Balan Apr 05 '20 at 07:19
Or slice, or spread, etc. `forEach` ignores its return value. – CertainPerformance Apr 05 '20 at 07:20
@CertainPerformance, i don't want to get an array, i want to get all values from array. The typeof of test should be a string. It is possible to do this? – AskMen Apr 05 '20 at 07:23
`.join` by newlines? – CertainPerformance Apr 05 '20 at 07:24
