Sort an array of objects based on a specific property (dollars) in JavaScript

Question

Sort an array of objects based on a specific property (dollars) in JavaScript

I'm really struggling to solve this problem. In my Vue.js application, I have an array of objects structured like this:

var food = [{'name':'apples','price':'222.30'},{'name':'bananas','price':'99.30'},{'name':'oranges','price':'199.30'}];

When attempting to sort by price, I've tried the following methods:

return food.sort((a, b) => (a.price > b.price) ? 1 : -1);
AND
return _.orderBy(food, 'price')

Unfortunately, it seems that the sorting interprets $99.30 as higher than $222.30, possibly due to the numeric values within the prices.

Any advice or guidance on how to correctly order from largest to smallest and vice versa would be greatly appreciated!

To properly sort the food items, make sure to convert the price into numerical values before using them in the sort function.

return food.sort((item1, item2) => parseFloat(item1.price) -  parseFloat(item2.price));

Simply utilize Numbers

let groceries= [{'name':'grapes','price':'55.50'},{'name':'pears','price':'44.20'},{'name':'watermelon','price':'100.75'}];


groceries.sort((x, y) => (Number(x.price) > Number(y.price)) ? 1 : -1);

console.log(groceries);

Answer №4

Your sorting algorithm is not producing the expected results because it compares prices as strings.

var products = [{'name':'apples','price':'222.30'},{'name':'bananas','price':'99.30'},{'name':'oranges','price':'199.30'}];

function comparePrices(a, b) {
  if ( parseFloat(a.price) < parseFloat(b.price) ){
    return -1;
  }
  if ( parseFloat(a.price) > parseFloat(b.price) ){
    return 1;
  }
  return 0;
}

products.sort(comparePrices);

or

products.sort((a, b) => (parseFloat(a.price) > parseFloat(b.price)) ? 1 : -1);

Storing the prices as strings creates complexity. The comparison process involves analyzing each price character by character, from left to right.

To streamline the code, consider converting the prices to floats:

return food.sort((a, b) => parseFloat(a.price) - parseFloat(b.price));
