const names = ['John', 'Paul', 'George', 'Ringo', 'John'];
let unique = [...new Set(names)];
console.log(unique); // 'John', 'Paul', 'George', 'Ringo'let arr = [1,2,3,1,1,1,4,5]
let filtered = arr.filter((item,index) => arr.indexOf(item) === index)
console.log(filtered) // [1,2,3,4,5]const myArray = [2,5,6,2,2,4,5,3,3];
const uniqueArray = [...new Set(myArray)];
console.log(uniqueArray);// usage example:
var myArray = ['a', 1, 'a', 2, '1'];
var unique = myArray.filter((v, i, a) => a.indexOf(v) === i);
console.log(unique); // unique is ['a', 1, 2, '1']
Run code snippetuniqueArray = a.filter(function(item, pos) {
return a.indexOf(item) == pos;
})
unique = [...new Set(arr)]; // where arr contains duplicate elements
