> When i store an integer as an array element it take up 32 bits? 

That is not a question you should ask us.

array elements store variable values, 
that can be strings, arrays, objecs of floating-point numbers.

Integer is not a variable type in Javascript.

If you decide to store "integer values" [not "integers"] as Javascript 
floating-point numbers, even then the internal "it takes up 32 bits?" 
[grammar corrected] is unimportant to you and even might be different for 
different Javascript implementations. The only thing you need to know is the 
maximum positive and negative integer values allowed:

<script type='text/javascript'>

var N = Number.MAX_SAFE_INTEGER;

document.write(N); // 9007199254740991
document.write('<br>');

document.write(N + 1); // 9007199254740992
document.write('<br>');

document.write(N + 2); // 9007199254740992
document.write('<br>');

document.write( N === Math.pow(2, 53)-1 ); // true
document.write('<br>');
document.write('<br>');

N = Number.MIN_SAFE_INTEGER;

document.write(N); // -9007199254740991

document.write('<br>');

document.write(N - 1); // -9007199254740992
document.write('<br>');

document.write(N - 2); // -9007199254740992
document.write('<br>');

</script>
