Actually it’s not an array but a plain object; you can directly access its properties using the dot notation like so:
var filters = getFilters()
console.log(filters.level)
console.log(filters.location)
So you probably won’t need individual variables. Or if you need to convert it back to an array of key / value pairs for iteration, you can use Object.entries():
// This will give you something like
// [['level', '4'], ['location', '2']]
console.log(Object.entries(filters))
