I think your third example won't work because in the first mapping console.log will not return anything, so you will have an array of undefineds for second map function. I might be wrong but I think it's going to be like this.
Yep, you can easily test this in the dev tools with [1, 2, 3].map(console.log) and it retuns an array of undefined
[1, 2, 3].map(console.log)
