// Set the variables R, C, and U equal to 'replace', 'charAt', and 'toUpperCase'
// Replace searches a string and replaces characters
// charAt finds the char at a certain position
// toUpperCase makes things uppercase

R="replace",
C="charAt",
U="toUpperCase";

// alert causes an on-screen pop-up, needed for this competition because I have to write to STDOUT
alert(

// a[R] means the same as a.replace() see variable `R` above
a[R](

// This regexp looks for any of those words (COMMA, SEMICOLON, etc) that match the pattern "^WORD"
/\^((COMMA)|(SEMICOLON)|(COLON)|(PERIOD)|(BANG)|(DASH)|(HYPHEN)|(EMDASH)|(OPENQUOTE)|(CLOSEQUOTE))/g

// Because I'm using replace() I can declare the replacement as a function
// In order to do so, I'm using ECMA 6's arrow functions
// Arrow functions follow the syntax of:
/* 
([param] [, param]) => {
   statements
}

param => expression
*/
// So, I'm essentially saying, a.replace([regexp], function(args) {if (a) { do things } else if { do more things} })

// This is the same thing, except I'm using different regexps
// These say, match any string that's something like "[space][punctuation]"
// I have to list all these in order because they're being mapped to my arguments
// So the (\.) is mapped to argument 'v', hence the v?"."

// Again, same as above except this time I'm taking the [C]haracter at position (0) and making it [U]ppercase() then taking the rest of the string and tacking it on to the end of that character
[R](/.+?[\.\?\!](\s|$)/g,(t=>t[C](0)[U]()+t.substr(1)))

// Nearly the same... figure it out >:)
