How costly is .NET reflection?
...flection when it is used to get or set an objects properties.
I devised a test which I think is fair since it caches all the repeating calls and only times the actual SetValue or GetValue call. All the source code for the performance test is in bitbucket at: https://bitbucket.org/grenade/accessorte...
What is InputStream & Output Stream? Why and when do we use them?
...stream.close();
You can read from other different input sources:
byte[] test = new byte[] {0, 0, 1, 0, 0, 0, 1, 1, 8, 9};
DataInputStream stream = new DataInputStream(new ByteArrayInputStream(test));
int value0 = stream.readInt();
int value1 = stream.readInt();
byte value2 = stream.readByte();

Converting a list to a set changes element order
...[2, 210]
If you need a data structure that supports both fast membership tests and preservation of insertion order, you can use the keys of a Python dictionary, which starting from Python 3.7 is guaranteed to preserve the insertion order:
>>> a = dict.fromkeys([1, 2, 20, 6, 210])

Finding Variable Type in JavaScript
...umber, boolean, object, string and symbols. You can also use instanceof to test if an object is of a specific type.
function MyObj(prop) {
this.prop = prop;
}
var obj = new MyObj(10);
console.log(obj instanceof MyObj && obj instanceof Object); // outputs true
