JavaScript Interview Programming Questions: -
 (1) write a program to take an array input and return the two arrays one of unique numbers and one for duplicate numbers: -

const findDuplicateNumber=(a)=>{
    const duplicateObject = {};
    const uniqueArray = []
    const duplicateArray = []
    for(let numbers of a){
     duplicateObject[numbers] = (duplicateObject[numbers] || 0) + 1
    }
    for(let keys in duplicateObject){
        if(duplicateObject[keys] > 1){
            duplicateArray.push(keys)
        }else{
            uniqueArray.push(keys)
        }
    }
    return {duplicateArray, uniqueArray}
}
testingArray=[2,4,5,55,16,22,55,16,5]
const duplicateNumber = findDuplicateNumber(testingArray)
console.log(duplicateNumber.duplicateArray)
console.log(duplicateNumber.uniqueArray)


(2) Write a program to find if a string is an anagram or not?


const isAnagram=(name1, name2)=>{
    if(name1.length != name2.length){
        console.log(name1,"and",name2, "can not be Anagram")
    }else{
        let counter = {}
        for(let numbers of name1){
            counter[numbers] = (counter[numbers] || 0) + 1
        }
        for(let numbers2 of name2){
            if(!counter[numbers2]){
                console.log("this can not be anagram===")
                return 
            }
            counter[numbers2] -= 1
        }
        console.log("This both strings are anagram")
    }

}
const name1 = "jokar";
const name2 = "okelr";
isAnagram(name1,name2);
