//just var unique = new Set(arr) wont be an arrayjavascript find unique values in array
// usage example:
var myArray = ['a', 1, 'a', 2, '1'];

// unique is ['a', 1, 2, '1']array unique values javascript
const myArray = ['a', 1, 'a', 2, '1'];
const unique = [...new Set(myArray)]; // ['a', 1, 2, '1']javascript get unique elements in array
