Suppose we have the following data structure:
var lowestPricesCars =
{
HondaC:
{
owner: "",
price: 45156
},
FordNew:
{
owner: "",
price:4100
},
HondaOld:
{
owner: "",
price: 45745
},
FordOld:
{
owner: "",
price: 34156
},
}
How can I sort the cars based on their prices?
If you need clarification on the question, feel free to leave a comment.
Thank you!
const keysArray = Object.keys(listOfLowestPrices)
const sortedKeysByPrice = keysArray.sort((a,b) => {
return listOfLowestPrices[a].price - listOfLowestPrices[b].price;
});
let carsSortedByPrice = {}
sortedKeysByPrice.forEach(key => carsSortedByPrice[key] = listOfLowestPrices[key])
To reverse the order:
return listOfLowestPrices[b].price - listOfLowestPrices[a].price;
If you want to accomplish this task efficiently, you can use ES6 features such as Object.entries, Array.sort, and Array.reduce.
It's important to note that the order of object keys is not guaranteed and may vary between different browsers, so relying on it is not recommended.
const data = { HondaC: { owner: "", price: 45156 }, FordNew: { owner: "", price:4100 }, HondaOld: { owner: "", price: 45745 }, FordOld: { owner: "", price: 34156 } }
console.log(Object.entries(data)
.sort((a,b) => a[1].price - b[1].price) // for DESC b[1].price - a[1].price
