petsel / Boolean.isTrue.isFalse.js

Last active September 7, 2020 11:14

	/**
	* `Boolean.isTrue` / `Boolean.isFalse` is a fun implementation of Smalltalk's [https://en.wikipedia.org/wiki/Smalltalk]
	* `ifTrue` / `ifFalse` control structures [https://en.wikipedia.org/wiki/Smalltalk#Control_structures].
	*
	* It is nothing one would really desire in JavaScript unless one is looking for an alternative to its native `if...else`
	* statement and has deeply fallen in love with using function expressions all along.

petsel / localeCompare.defaultCompare.js

Created February 15, 2021 17:16

provides a `localeCompare` based compare function which can be used like `[/* ... */].sort(localeCompare)`

	function defaultCompare(a, b) {
	return ((a < b) && -1) \|\| ((a > b) && 1) \|\| 0;
	}
	// function localeCompare(a, b) {
	// return a.localeCompare
	// ? a.localeCompare(b)
	// : defaultCompare(a, b);
	// }

	// - supports additional `…[, locales[, options]` argument binding
