How to use it:

1. Include the minified version of the Balzac.js library on the page.

<script src="balzac.min.js" defer></script>

2. Enhance JavaScript’s Number object.

// checks if a number is between two values, bounds included
number.isBetween(min, max);
// checks if a number is between two values, bounds excluded
number.isBetweenExclusive(min, max);

3. Enhance JavaScript’s Math object.

// returns a numeric expression rounded to a specified number of fractional digits
Math.roundTo(x, decimals);

4. Enhance JavaScript’s String object.

// hecks if a string is all in uppercase letters.
string.isUpperCase();
// checks if a string is all in lowercase letters.
string.isLowerCase();
// returns a string converted to title case (every major word capitalized).
string.toTitleCase();
// returns a string converted to sentence case (first word of every sentence capitalized).
string.toSentenceCase();
// returns a string with leading and trailing white space and line terminator characters removed from each line.
string.trimAll();
// returns a string truncated to the nearest word, with a trailing ellipsis if needed.
string.truncate(max);
// returns an HTML string converted to plain text, with all HTML tags removed.
string.toPlainText();
// returns a string with new lines converted to HTML line breaks.
string.nl2br();
// returns a string with new lines converted to HTML paragraphs.
string.nl2p();

5. Enhance JavaScript’s Date object.

/**
 * Adds duration constants to new Date.DURATION object for converting delays into milliseconds.
 *  SECONDE: 1 second in milliseconds.
 *  MINUTE:  1 minute in milliseconds.
 *  HOUR: 1 hour in milliseconds.
 *  DAY: 1 day in milliseconds.
 */
setTimeout(function, 3 * Date.DURATION.MINUTE);
// checks if a date is between the specified interval, bounds included.
date.isBetween(start, end);
// checks if a date is between the specified interval, bounds excluded.
date.isBetweenExclusive(start, end);
// returns a new Date that adds the specified number of milliseconds to the value of this instance.
date.addMilliseconds(value);
// returns a new Date that adds the specified number of seconds to the value of this instance.
date.addSeconds(value);
// returns a new Date that adds the specified number of minutes to the value of this instance.
date.addMinutes(value);
// returns a new Date that adds the specified number of hours to the value of this instance.
date.addHours(value);
// returns a new Date that adds the specified number of days to the value of this instance.
date.addDays(value);
// returns a new Date that adds the specified number of months to the value of this instance.
date.addMonths(value);
// returns a new Date that adds the specified number of years to the value of this instance.
date.addYears(value);

6. Enhance JavaScript’s RegExp object.

/**
 * Adds predefined input RegExp patterns to new RegExp.PATTERN object.
 *  EMAIL
 *  EMAILS
 *  PHONE:
 *  PASSWORD
 *  PASSPORT
 *  IBAN
 *  POSTCODE
 */
RegExp.PATTERN.EMAIL.test(string);

7. Enhance JavaScript’s Navigator object.

// checks if user navigator is Google Chrome.
navigator.isChrome;
// checks if user navigator is Microsoft Edge.
navigator.isEdge;
// checks if user navigator is Mozilla Firefox.
navigator.isFirefox;
// checks if user navigator is Opera.
navigator.isOpera;
// checks if user navigator is Apple Safari.
navigator.isSafari;

8. Manipulate browser cookies.

// returns a browser cookie value (undefined if not existing).
string = document.getCookie(name);
// sets a browser cookie.
document.setCookie(name, value, expires);
// deletes a browser cookie.
document.removeCookie(name);

9. Enhance JavaScript’s File object.

/**
 * adds size constants to new File.SIZE object to help converting file sizes from bytes.
 *  KILOBYTE
 *  MEGABYTE
 *  GIGABYTE
 *  TERABYTE
 */
megabytes = document.getElementById('fileInput').files[0].size / File.SIZE.MEGABYTE;

10. Encode/decode HTML.

string = WebUtility.htmlEncode(string);
string = WebUtility.htmlDecode(string);

11. Add a new case attribute to all input elements to force text case (“none”, “lower”, “upper”, “title” or “sentence”).

document.getElementById('input').case;

12. Get the password strength.

/**
 * Returns the password strength from HTMLInputElement.PASSWORD_RATING.EMPTY to HTMLInputElement.PASSWORD_RATING.STRONG.
 *  EMPTY:      Empty.
 *  SHORT:      Less than 8 characters.
 *  WEAK:       One or two of the PASSWORD_RATING.GOOD criteria.
 *  MEDIUM:     Three of the PASSWORD_RATING.GOOD criteria.
 *  GOOD:       At least 1 lowercase letter, 1 uppercase letter, 1 digit and 1 special character.
 *  STRONG:     All PASSWORD_RATING.GOOD criteria and greater than or equal to 12 characters.
 */
document.getElementById('passwordInput').getPasswordRating();

13. Return a static node list containing all HTML output elements associated with the input.

document.getElementById('input').getOutputs();
