maximum call stack size exceeded on converting file

Question

I am converting a large byte array into a string using

 var arrayBuffer = e.target.result,
          array = new Uint8Array(arrayBuffer);
 binaryString = String.fromCharCode.apply(null, array);

Here e.target.result is a image. It is working properly but if image size is bigger i'll get error maximum call stack size exceeded. How can i resolved this ??

Thanks in advance........

var base64 = btoa(new Uint8Array(arrayBuffer).reduce(
    function (data, byte) {
        return data + String.fromCharCode(byte);
    },
    ''
));
