Convert string into variable in array automatically

I have a problem when I\m trying to convert a string to a variable in an array.

The variables are:

const n = 1; const s = -1;

The array string:

let walk = ['n', 's', 'n', 's', 'n', 's', 'n', 's', 'n', 'n']; 

I want to convert automatically to this variable array:

let walk = [n, s, n, s, n, s, n, s, n, n];

I’m trying to split but the array still string not a var:

let text = walks.toString().split(',').join('-')
console.log(text)

>Solution :

You could put s and n into an object.

const variables = {
  n: 1,
  s: -1
};

let walk = ['n', 's', 'n', 's', 'n', 's', 'n', 's', 'n', 'n'];

console.log(
  walk.map(variable => variables[variable])
)
