I have an array like var aa = [a,b,c,d,e,f,g,h,i,j,k,l]; I wanted to remove element which is place on even index. so ouput will be line aa = [a,c,e,g,i,k];

I tried in this way

for (var i = 0; aa.length; i = i++) {

if(i%2 == 0){

    aa.splice(i,0);

}

};

But it is not working.

you can remove all the alternate indexes by doing this

var aa = [a, b, c, d, e, f, g, h, i, j, k, l];



for (var i = 0; i < aa.length; i++) {

  aa.splice(i + 1, 1);

}



console.log(aa);

or if you want to store in a different array you can do like this.

var aa = [a, b, c, d, e, f, g, h, i, j, k, l];



var x = [];

for (var i = 0; i < aa.length; i = i + 2) {

  x.push(aa[i]);

}



console.log(x);
