I'm very confused at this occurrence derp

How is

if (grid[0].sort()) {
      console.log(true)
  }

if (grid[0].sort()) {
      console.log(true)
  }

actually sorting grid[0]? is that a normal thing? I do not understand whats going on

the if statement is actually sorting grid whereas I'm just trying to check if grid is sorted

yes, because you're calling .sort(), and the if statement is comparing what that returns .sort() does not do any kind of a "is this sorted?" check

and there really isn't an easy way to check if an array is sorted at least not any kind of built-in API

yeah, so at that point you have to do something like what iggy showed the point is that there is no generic "is this sorted" function the answer to "is this sorted" entirely depends on what is inside the array, and that's specific to your app so yeah, you most likely would need to do some kind of pairwise comparisons all the way down the array
