How to pass the result to an object as numbers?

Question

JavaScript

Good day.
Tell me how to make the array result in numbers, not strings, and the result can be transferred to an object (for example, coordinates)?


const loc = {
lat: [35.65000, 35.70000],
lng: [139.70000, 139.80000]
};
const getRandomLocation = loc => _ => {
const [lat, lng] = Object.values(loc).map(([min, max]) => (Math.random() * (max - min) + min) .toFixed(5));
return [lat, lng]
};
const RandomLocation = getRandomLocation(loc);
for (let i = 0; i < 1; i++)
RandomLocation()

Answer 1

Put + in front of the variable
Example

let a = "12";
let b = +a;
console.log(typeof(a),typeof(b));

Option 2
Example:

let a = "12";
let b = Number(a);
console.log(typeof(a),typeof(b));
