Example 1: javascript find unique values in array
var myArray = ['a', 1, 'a', 2, '1'];
var unique = myArray.filter((v, i, a) => a.indexOf(v) === i);
Example 2: array unique values javascript
const myArray = ['a', 1, 'a', 2, '1'];
const unique = [...new Set(myArray)];
Example 3: javascript get unique values from array
const myArray = [1,2,3,1,5,8,1,2,9,4];
const unique = [...new Set(myArray)];
const myString = ["a","b","c","a","d","b"];
const uniqueString = [...new Set(myString)];
Example 4: 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);
Example 5: get only unique values from array javascript
arr = [2, 2, 2, 1, 3, 3, 3,3, 4, 5];
arr = arr.sort().filter((item,i)=>!(arr[i] == arr[i+1] || arr[i-1]==arr[i]));
console.log(arr);
