I have a number of variables with values:
apples_count = 1;
oranges_count = 4;
bananas_count = 2;
I want to store them in an array (eg fruits = []) so I can order them by value, ie
[oranges_count, bananas_count, apples_count]
If I attempt to add the variable oranges_count using
fruits.push(oranges_count);
Then the variable value 4 is added but not the variable itself.
How can I store the variables in an array so I can sort them by value?
Don't use separate variables, use an array of objects.
const fruits = [
{type: "apple", count: 1},
{type: "orange", count: 4},
{type: "banana", count: 2}
];
fruits.sort((a, b) => a.count - b.count);
console.log(fruits);You have 3 standalone variables with similar functionality. Consider using an object or an array instead, stored in a single variable. Then you can use array methods on the array to sort and retrieve the ordered counts, eg:
const counts = {
apples: 1,
oranges: 4,
bananas: 2,
};
const sortedEntries = Object.entries(counts).sort((a, b) => a[1] - b[1]);
for (const entry of sortedEntries) {
console.log(entry);
}With the above, to change a particular count, just do something like counts.apples = 5.
Or, using the array method from the beginning:
const fruits = [
{ name: 'apple', count: 1 },
{ name: 'orange', count: 4 },
{ name: 'banana', count: 2 },
];
const sortedFruits = fruits.sort((a, b) => a.count - b.count);
for (const fruit of sortedFruits) {
console.log(fruit);
}To change the count of an object in the above array, either .find the object with the name you want and assign to its count property:
fruits.find(({ name }) => name === 'apple').count = 10;
Or create an object like above, mapping each fruit name to its object.
Store an object instead of only the value. For example, you could use something like this:
var apples = {
amount: 1,
name: 'apple',
type: 'fruit'
};
var oranges = {
amount: 4,
name: 'orange',
type: 'fruit'
};
var bananas = {
amount: 2,
name: 'banana',
type: 'fruit'
};
var collection = [
apples,
oranges,
bananas
];
var sorted_collection = collection.sort(( first, second ) => first.amount - second.amount );
console.log( sorted_collection );
