Here I am able to return one value return fruit === 'cherries'
, how can I return two values , such as I tried return [fruit==='cherries', fruit==='bananas']
, How can I return two values.
var inventory = ['apples','bananas','cherries'];
function findCherries(fruit) {
return fruit === 'cherries' ;
}
console.log(inventory.find(findCherries));
You could use a logical OR -> ||
and Array.filter
var inventory = ['apples', 'bananas', 'cherries']; function findCherries(fruit) { return fruit === 'cherries' || fruit === 'bananas'; } console.log(inventory.filter(findCherries));
You could fiter it with an array of the wanted items.
function findFruits(fruits) { return fruit => fruits.includes(fruit); } var inventory = ['apples', 'bananas', 'cherries']; console.log(inventory.filter(findFruits(['bananas', 'cherries'])));
If your inventory is below and u know which one is fruit then
function findMyInventory(type) {
var inventory = ['apples', 'bananas', 'cherries', 'beans', 'roots'];
var list = [];
if ( type == 'fruits') {
list.push(inventory.slice(0,2) );
} else if ( type == 'vegetables' ) {
list.push( inventory.slice(3,4) ) ;
}
return list;
}
if your list as below
var inventory = [
{ type: 'fruit' , name : 'apples'},
{ type: 'fruit' , name : 'bananas'},
{ type: 'fruit' , name : 'cherries'},
{ type: 'vegetable' , name : 'beans'},
{ type: 'vegetable' , name : 'roots'}
];
function findMyInventory(type) {
var myList = [];
for ( var item of inventory) {
if ( type == item.type) {
myList.push( item);
}
}
return myList;
}
