Caeser Cipher decryption replaces a letter another with an inverse alphabet shift a previous letter.

JavaScript Prototypes Every javascript has a prototype and it is also an object.

All javascript objects inherit the properties and methods from their prototype. Objects created using an object literal, or eith object(), inherit from a prototype called object.prototype.

All javascript object(Data, Array, RegExp, Function, ..) inherit from the object.prototype.

.Filter() method creates a new array with all elements that pass the test.
