I have one array that holds multiple arrays that contain two numbers. I want to sort this array by ascending numbers.
This is how I'm creating the array of arrays. I start with two arrays, one holding the key and one holding the value. Then I join those two arrays into an object of key value pairs. The I convert that object into the new array of arrays.
keySliceArray.forEach((key, i) => result[key] = valueSliceArray[i])
console.log(result)
// This is the output of result

I want it to look like this. I want sort the newArray variable in ascending order by the first number in each subsequent array.

I have tried using the sort method like this but for some reason this just returns the original array. Any advice on how to achieve this is greatly appreciated!
let sortArray = newArray.sort(function (a, b) {
return a - b
})
