How to iterate through an array of objects with checking the key of iteratees with the state?

Variable br must consist only of bool values. Which have been gotten by looping through the first array.

state ={
    nonRelated: this.props.non_related.value,
    1:true,
    2:true,
    3:false,
    4:false,
    5:true,
   //  etc.
}

let ar = [1,2,3,4,5,6,....20];
let br = ar.map(el => {
return state.el
})

Another example:

I need to filter the array, if the key in the iteratee (which is an object) in the state has the value "true".

`state[el]` not `state.el`. Also `.forEach()` doesn't pay attention to the return value of the callback function. You probably want `.filter()`. – Pointy Feb 06 '19 at 14:26
I think you meant `map` not `forEach` – Bergi Feb 06 '19 at 14:27
Yes, but it doesn't make much difference :) – Sth Feb 06 '19 at 14:28
@Pointy yes, in my actual code it's .filter(), which is in the photo. – Sth Feb 06 '19 at 14:29
