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

Question

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".
