# Symmetric Difference*

Hello!, I want to push the elements of the next array in the args in the newArr.

I could filtered the newArr,

But, How can I introduce the elements which are not included in the newArr.

``````function sym(...args) {

let newArr=[];

let arr0=args[0];

let arr1=args[1];

let lengthOfArgs=args.length;

if(lengthOfArgs==2){

for(let i=0;i<arr1.length;i++){

if(!arr0.includes(arr1[i]) && !newArr.includes(arr1[i]) ){

newArr.push(arr1[i])

}

}

for(let i=0;i<arr0.length;i++){

if(!arr1.includes(arr0[i]) && !newArr.includes(arr0[i]) ){

newArr.push(arr0[i])

}

}

return newArr.sort((a,b)=>a-b)

}else{

for(let i=0;i<arr1.length;i++){

if(!arr0.includes(arr1[i]) && !newArr.includes(arr1[i]) ){

newArr.push(arr1[i])

}

}

for(let i=0;i<arr0.length;i++){

if(!arr1.includes(arr0[i]) && !newArr.includes(arr0[i]) ){

newArr.push(arr0[i])

}

}

for(let i=2;i<args.length;i++){

for(let j=0;i<newArr.length;j++){

if(args[i].includes(newArr[j])){

newArr=newArr.filter(e=>!args[i].includes(e))

}else{

newArr=newArr.push(args[i][j])

}

//if(!newArr.includes(args[i][j])){

//        newArr.push(newArr[i][j])

//}

}

}

}

}

sym([3, 3, 3, 2, 5], [2, 1, 5, 7], [3, 4, 6, 6], [1, 2, 3], [5, 3, 9, 8], [1]);

Iâ€™ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the â€śpreformatted textâ€ť tool in the editor (`</>`) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (â€™).

Why is this not working?

console.log(newArr)
