A simple way to implement a validation by JavaScript currying
var above = function(limit){
return function(value){
return value > limit;
};
};
var isAbove10 = above(10);
console.log(isAbove10(5)); // false
console.log(isAbove10(8)); // false

An incrementally improved approach to a common JavaScript function/utility widely adopted all over. Returns the lowercase type or [[Class]] of a generic variable.
var typeOf = (function(Object, RegExp){
// WTFPL License - http://en.wikipedia.org/wiki/WTFPL

var toString = Object.prototype.toString,

Unknown === null ? 'null' : (

Parse CSS colors like 'hsla(32,50%,20%,0.4)' into RGB components
// Tested in Chrome 23, Firefox 16, and IE9 in standards mode (i.e. with <!DOCTYPE html>).
// Converts '#f00', 'red', 'hsl(0, 100%, 50%)' and 'rgb(255,0,0)' to {r:255,g:0,b:0}.
function cssColorToRGB(cssColor) {
var s = document.createElement('span')
document.body.appendChild(s)
s.style.backgroundColor = cssColor
var rgb = getComputedStyle(s).backgroundColor
document.body.removeChild(s)
var m = /^rgb\((\d+), (\d+), (\d+)\)$/.exec(rgb)

How to hang JavaScript (useful - to me - for slowing down code and testing)
function hang(n) {
var x = new XMLHttpRequest();
x.open('GET', 'http://hang.nodester.com/script.js?' + n, false);
x.send();
}
// usage: hang(2 * 1000);

Efficient callback management for window.onresize
(function( window ){
window.watchResize = function( callback ){
var resizing;
callback.size = 0;
function done()
{
var curr_size = window.innerWidth;
clearTimeout( resizing );
resizing = null;
// only run on a true resize
