Howdy all. I've got this sort function which prioritizes truthy values in an array:

    truthyFirst: (array, callback = emptyCallback) => {
      return array.sort((a, b) => {
        if (callback(a) && callback(b)) return 0;
        if (callback(b)) return 1;
        if (callback(a)) return -1;
      });
    },

    truthyFirst: (array, callback = emptyCallback) => {
      return array.sort((a, b) => {
        if (callback(a) && callback(b)) return 0;
        if (callback(b)) return 1;
        if (callback(a)) return -1;
      });
    },

Is there a better way to coerce the condition to its relevant value? e.g. a && b -> 0, a -> -1, b -> 1

Got it Changed Lol, caught in the act Fair enough Thank you Another question, is there a better way to handle the emptyCallback bit? Currently I've got:

const emptyCallback = (...args) => args;

const emptyCallback = (...args) => args;

The idea being that if a callback is not provided to the function, it will return the parameters Are my arguments coerced into a boolean? Ah okay Well The value will always be a boolean

   arrayFunctions.sort.truthyFirst(products, (product) => {
      return product.metadata.status == 'In Stock';
    })

   arrayFunctions.sort.truthyFirst(products, (product) => {
      return product.metadata.status == 'In Stock';
    })

This is how I want to use the function Makes sense Perfect That's what I'm looking for Thank you I implemented both
