The Array.findindex function was originally created by Google (and later by the brilliant Tim Bray) in order to index into a sorted array. This is why array.findindex(item, index) returns -1.
If you haven’t already heard of array.findindex, then here’s a good reason why: array.findindex returns the last element in an array’s array, not the first. The first element in an array is the entire array.
A friend of mine who works on the project at Apple, has a website called “Arrays”. Google has an array.html page, which is a complete list of array items. To get around the issue of the numbers being array objects; the first item in the array is the first element in the array, and the second is the second element in the array. The first two elements are not necessarily the same element, but the second one is the first element in the array.
It’s not clear what will happen with this. If it’s just an array object, then it’s easy to change. If that’s the case, then the second element in the array will be the second element in the array.

If its the only element of the array, then it will be the first element of the array.
A for loop is basically a way to loop over a set of numbers with a given set of values. For instance, given a set of numbers we can say, “for each number in the set, check if the value is in the set.
Array indexes are not always numeric. In fact, they’re not even always numbers at all. You can use array indexes that are strings, like index.forEach( x => console.log(x) ) or index.forEach( x => x ), but it’s also possible to use indexes that are numbers, like index.includes( x ). So, let’s work with the for loop example above.
