var arr=[1,4,6,4,2]; for(var i=0; i<3; i++){ arr[i]=arr[i]+arr[i+2]; } document.write(arr[3]);

What is the output of this code? var arr=[1,4,6,4,2]; for(var i=0; i<3; i++){ arr[i]=arr[i]+arr[i+2]; } document.write(arr[0]); https://code.sololearn.com/WggijYpSg59h/?ref=app

/* Print each step out and compare with the result: */ let arr=[1,4,6,4,2]; for(let i=0; i<3; i++){ console.log(`${i}: ${arr[i]}+${arr[i+2]}`); // print each iteration arr[i]=arr[i]+arr[i+2]; } console.log(arr); // print result
