// app.js

Array.prototype.unique = function() {
  let arr = [];
  for(let i = 0; i < this.length; i++) {
      if(!arr.includes(this[i])) {
          arr.push(this[i]);
      }
  }
  return arr; 
}

const ages = [26, 27, 26, 26, 28, 28, 29, 29, 30]
const uniqueAges = ages.unique()
console.log(uniqueAges)

Javascript unique array or dublicate array value find programs

  function uniqueAry(ary) {
    if (!Array.isArray(ary)) return `function paramiter only required on array!`
    // simple and old methods
    const uniqueAry = []
    const dubAry = []
    for (const arr of ary) {
      if (!uniqueAry.includes(arr)) {
        uniqueAry.push(arr)
      } else if (!dubAry.includes(arr)) {
        dubAry.push(arr)
      }
    }
    // modern new methods solve the problems

    // const uniqueAry = ary.filter((item, index, array) => array.indexOf(item) === index)
    // const dubArrays = ary.filter((item, index, array) => array.indexOf(item) !== index)
    // const dubAry = [... new Set(dubArrays)]

    return {uniqueAry,aryDublicateValue:dubAry}
  }
  const input = [1, 2, 2,2,2,2, 3, 4, 5,6,6,6,5,4,4, 5]
  const output = uniqueAry(input)
  console.log(output);
