I have a issue in array in javascript

Question

function isWin(arr){
    const conditions=[[1,2,3],[4,5,6],[7,8,9],[1,4,7],[2,5,8],[3,6,9],[1,5,9],[3,5,7]]; //wining constions
    arr=arr.sort();
    let result=conditions.forEach((eachCondtions)=>{
    console.log(eachCondtions===arr)        //false
    })


isWin([4,5,6]);
