Hello with the following line of code, how do I modify it and print the amount of each type of fruit using the same function?
var fruits = ["Banana", "Orange", "Apple", "Mango","Orange", "Orange",
"Apple", "Mango"];
var cant = fruits.filter(function(value) {
return value == "Orange";
})
console.log(cant.length);
You can create a function that accepts an Array and an x element to search, and returns the number of elements x found equal
var fruits = ["Banana", "Orange", "Apple", "Mango","Orange", "Orange",
"Apple", "Mango"];
function myFunction(myArr, xelement ) {
return (myArr.filter(x => x == xelement )).length;
}
console.log(myFunction(fruits,"Orange"));
There are other ways to count the number of times an element repeats itself within an array, but using your code you can do the following by iterating each element and checking if the array has already been filtered by that element.
var fruits = ["Banana", "Orange", "Apple", "Mango", "Orange", "Orange", "Apple", "Mango"
];
var counted = [];
fruits.forEach(function(element) {
if (!counted.includes(element)) {
var cant = fruits.filter(function(value) {
return value == element;
}).length;
counted.push(element);
console.log(element + " = " + cant);
}
});Something simple could be using encapsulating your filter
const frutas = ["Banana", "Orange", "Apple", "Mango","Orange"];
const contarFrutas = (valor, listaDeFrutas) => (
listaDeFrutas.filter(fruta => fruta === valor).length
);
console.log(
contarFrutas('Banana', frutas)
);
console.log(
contarFrutas('Orange', frutas)
);
var a = ["Banana", "Orange", "Apple", "Mango","Orange"].reduce(function (array, index) {
array[index] ? array[index]++ : array[index] = 1
return array;
}, {});
console.log(a)
