I have an array:
const arr = [
{id: 1, text: "hello", likes: [1,2,5]},
{id: 2, text: "text", likes: []},
{id: 3, text: "example", likes: [1]}
]
how to filter it according to the length of likes array i.e array should be like this:
const arr = [
{id: 1, text: "hello", likes: [1,2,5]},
{id: 3, text: "example", likes: [1]},
{id: 2, text: "text", likes: []},
]
You could use Array.prototype.sort() with parameters a,b and compare the length property of the likes property
READ MORE HERE: javascript Array.prototype.sort
const arr = [
{id: 1, text: "hello", likes: [1,2,5]},
{id: 2, text: "text", likes: []},
{id: 3, text: "example", likes: [1]}
]
arr.sort(function(a,b) {
return b.likes.length - a.likes.length;
});
for(let a = 0; a < arr.length; a++){
console.log(arr[a]);
}
