Example 1: javascript array unique values
var arr = [55, 44, 65,1,2,3,3,34,5];
var unique = [...new Set(arr)]
//just var unique = new Set(arr) wont be an array
Example 2: javascript find unique values in array
// usage example:
var myArray = ['a', 1, 'a', 2, '1'];
var unique = myArray.filter((v, i, a) => a.indexOf(v) === i);
// unique is ['a', 1, 2, '1']
Example 3: array unique values javascript
const myArray = ['a', 1, 'a', 2, '1'];
const unique = [...new Set(myArray)]; // ['a', 1, 2, '1']
Example 4: unique values in array javascript
let uniqueItems = [...new Set(items)]
Example 5: javascript get distinct values from array
const categories = ['General', 'Exotic', 'Extreme', 'Extreme', 'General' ,'Water', 'Extreme']
.filter((value, index, categoryArray) => categoryArray.indexOf(value) === index);
This will return an array that has the unique category names
['General', 'Exotic', 'Extreme', 'Water']
Example 6: javascript remove duplicates from array
function toUniqueArray(a){
var newArr = [];
for (var i = 0; i < a.length; i++) {
if (newArr.indexOf(a[i]) === -1) {
newArr.push(a[i]);
}
}
return newArr;
}
var colors = ["red","red","green","green","green"];
var colorsUnique=toUniqueArray(colors); // ["red","green"]
