There is an area where I am most amazed at its progression, and that is with Encryption. For years, this area was pretty much dominated by the C and C++ languages (to which I am also a seasoned developer in), but now that JavaScript has made its way to the server, it is becoming recognized as a potential contender to this domination. Our encrypText helper function reads the text and the shift value that we introduce in our form and convert it to Number. Then with the map function invokes the encrypt function for each character. To do this, first, we turn the input string sourceTest from string to array using the spread operator.
