As many people know, JavaScript doesn’t really have classes but you can mimic some of their behavior with the prototypal setup available in JavaScript. Still, a lot of times it is just easier when you have a function that does most of the work for you. For that reason, I Read more…
Probably due to it being so late, I was looking for code to uncamelize (undo camel-casing) any string. I came across what claimed to be a solution in PHP but unfortunately did nothing but lowercased my string. Therefore I decided to write my own solution: Believe it or not, the Read more…
I have been working on something I am calling JS-Proofs (or jPaq Proofs). While working on the menu I was faced with the annoying issue of either not having whitespaces between my elements in the markup or removing them some other way. Since my favorite language is JS, I decided Read more…
If you should ever need to parse a number into an array of bits or a different base you can use the following function: var splitNumber = (function(MAX) { for (; MAX + 1 – MAX == 1; MAX *= 2){} return function (num, radix) { // Validate num num Read more…
The other day I kind of just wanted a reason to write a Gist and embed it on my site using this method. What I came up with was a quick way to make all functions appear to be native: https://gist.github.com/9240810 Here is an example of what happens: I have Read more…
One simple function that is on the roster to be released in EcmaScript 6 is String.prototype.repeat. The following can be used to define it in browsers which don’t currently have it defined natively: Here are some examples of using this function (modified from the originals found on MDN): There is Read more…
One thing that is common knowledge about JavaScript and other languages is that floating point numbers are not always stored the way you think. Also doing math with these numbers is even more iffy. One thing I recently wanted to do was effectively the opposite of parseInt(). In other words, Read more…
One thing that I always took for granted until last week was testing for negative numbers. What I mean is that I had no clue that -0 is actually different from 0. Interestingly enough when using strict equality to test the two values they still appear to be equal but Read more…
One function I didn’t think would be doable in most browsers was the Math.sign. My main worry was that on the MDN page it specifies a difference between negative zero and positive zero. After doing some research I found this page which helped me realize there is a way to Read more…
A function that is proposed to be added to EcmaScript 6 is Array.of(). This function will be used to create an array of the passed parameters. Since this function is available in some browsers but not in all, here is a block of code which when executed will define it Read more…
