// -----Data Types: STRING----- //

/* Strings are character or textual data strung together enclosed 
by either single or double quotes. */

var stri = "I'm a sequence of character data!";
console.log(stri);

/* Almost anything can be put within a string with the exception
of a number of special characters, such as the newline "\n" and
horizontal tab "\t". Since a string must be on a single line,
to type and log a newline character, precede it by another
backslash. The two will collapse into each other and type out the
intended text: */

var exStri = "I want to show you a (backslash n) \\n!"
// The double backlash causes them to collapse into one
console.log(exStri);

var newlineStri = "First line.\n Second line."; 
// "\n" by itself starts a new line.
console.log(newlineStri);

/* Individual characters of a string are zero-based indexed, 
and can have its contents altered by a number of methods; however,
those individual contents are immutable and cannot be directly 
altered after a string's creation: */

var nopeStri = "You can't alter my individual characters!";
nopeStri[0] = "P";
console.log(nopeStri); // Still logs "You..."

/* Altering the contents using a built-in method is possible: */

var re = /(\w+)\s(\w+)/;
var str = 'Devin Fields';
var newStr = str.replace(re, '$2, $1');
console.log(newStr); // logs "Fields, Devin"
