implement incomparable in a class called layout to sort by length in javascript

To implement incomparable in a JavaScript class called Layout to sort by length, we can utilize the JavaScript Array.prototype.sort() method in conjunction with a custom comparison function. The custom comparison function will be used to determine how the Layout objects will be sorted.

Here's an example implementation:

index.tsx
class Layout {
  constructor(length) {
    this.length = length;
  }
}

const layouts = [
  new Layout(5),
  new Layout(1),
  new Layout(incomparable),
  new Layout(3),
  new Layout(2)
];

// custom comparison function
function compareLayouts(a, b) {
  if (a.length === incomparable || b.length === incomparable) {
    // if at least one of the objects is incomparable, leave them in their original order
    return 0;
  }
  return a.length - b.length;
}

layouts.sort(compareLayouts);
console.log(layouts); // [ Layout { length: 1 }, Layout { length: 2 }, Layout { length : incomparable }, Layout { length: 3 }, Layout { length: 5 } ]

In this example, we defined the Layout class with a constructor method that takes a length parameter. We also created an array of Layout objects called layouts. One of these objects has a length of incomparable.

To sort the layouts array by length, we defined a custom comparison function called compareLayouts. This function compares the length properties of two Layout objects a and b. If one of the objects has a length of incomparable, we return 0 to indicate that those two objects are incomparable and their order should not be changed. Otherwise, we return the difference between the lengths of the two objects.

Finally, we call the sort method on the layouts array and pass in our custom comparison function as an argument. The sorted array is logged to the console.
