Exercise 1

create modules to implement this features

• convert string to title capitalized
• sanitize a string
• count word frequency

'use strict';


var stringIn = process.argv[2] || " escribe ";

var stringInArray = stringIn.split(" ");

stringInArray.forEach(function ( item, index, array ){
    var capital = firstLetter(item);
    var rest = restOfString(item);
    console.log(capital+rest);  
});


function firstLetter (stringIn) {
    return stringIn[0].charAt(0).toUpperCase();
}

function restOfString (stringIn){
    return stringIn.slice(1,stringIn.length);
}

module.exports = capitalLetter

function capitalize(str) {

    let aux;
    let arr = [];

    str.split(/ +/).map(function(word) {
        aux = word.substring(0, 1).toUpperCase() + word.substring(1, word.length).toLowerCase();
        arr.push(aux);
    });

    return arr.join(" ");
}
