Number类型统一按浮点数处理，64位存储，整数是按最大54位来算最大最小数的，否则会丧失精度；某些操作（如数组索引还有位操作）是按32位处理的~~
function roughSizeOfObject( object ) {
var objectList = [];
var stack = [ object ];
var bytes = 0;
while ( stack.length ) {
var value = stack.pop();
if ( typeof value === 'boolean' ) {
bytes += 4;
}
else if ( typeof value === 'string' ) {
bytes += value.length * 2;
}
else if ( typeof value === 'number' ) {
bytes += 8;
}
else if
(
typeof value === 'object'
&& objectList.indexOf( value ) === -1
)
{
objectList.push( value );
for( var i in value ) {
stack.push( value[ i ] );
}
}
}
return bytes;
}
