Some notes about conversion to number in javascript

javascript has lots of methods to convert any value to number

all methods could be divided into 2 groups: string and native methods
- String methods are parseInt and parseFloat
- Native mathods are Number and Math methods

all native methods behave the same way, sometimes with additional transform

If you've written any kind of validation on user input, like onkeypress then you'll know that sometimes you want to throttle the amount of times your function runs. A good example of this is Ajax based username validation - you don't want to hit the server on every key press, because most users will be able to write their name in around 1/10th of a second, so you should throttle the ajax request until the input is dormant for 100ms.

So with a bit of magic JavaScript making use of the ever useful closure JavaScript offers, we can create a simple method to handle this for us:

function debounce(fn, delay) {
  var timer = null;
  return function () {
    var context = this, args = arguments;
    clearTimeout(timer);
 timer = setTimeout(function () {

	const createLogger = (backgroundColor, color) => {
	const logger = (message, ...args) => {
	if (logger.enabled === false) {
	return;
	}

	console.groupCollapsed(
	`%c${message}`,
	`background-color: ${backgroundColor}; color: ${color}; padding: 2px 4px;`,
	...args

	\ // the escape character - used to find an instance of a metacharacter like a period, brackets, etc.
	. // match any character except newline
	x // match any instance of x
	^x // match any character except x
	[x] // match any instance of x in the bracketed range - [abxyz] will match any instance of a, b, x, y, or z
	\| // an OR operator - [x\|y] will match an instance of x or y

	// Generates a strong password of N length containing at least one lower case letter,
	// one uppercase letter, one digit, and one special character. The remaining characters
	// in the password are chosen at random from those four sets.
	//
	// The available characters in each set are user friendly - there are no ambiguous
	// characters such as i, l, 1, o, 0, etc. This, coupled with the $add_dashes option,
	// makes it much easier for users to manually type or speak their passwords.
