One of my favorite things about JavaScript is the ability to use certain functions to do unexpected things. The following shows you the code that could be used to imitate Prototype’s corresponding function: Basically the above code creates a new array has a length of the specified number plus one.

One of the things that I love about string manipulation is the existence of regular expressions. For this reason, I have decided to share a few examples that may help those who are learning about regular expressions so that can understand them a bit better. JavaScript – General Variable Name Read more…
I was surfing the internet a bit today and starting thinking about universally unique IDs. I came across this site which generates the UUIDs on the server side and then decided to make my own pseudo globally unique ID generator: You can use this function to generate as many UUIDs Read more…
As many of you may know, in JavaScript, you can define a date object by specifying a string that looks like a date. Recently I created a page using AJAX to get counter information, including the date/time that the page was hit. I thought that a pretty straight-forward format that Read more…
The following is an implementation of a binary search for arrays which gives you the ability to do fuzzy matches (default), exact matches, or specify your own comparison function: I used the following to test the normal execution of this binary function:
One thing that I came to grips with today is the fact that if an error occurs in one of the functions that was bound to the document’s ready pseudo-event (I say this because the event doesn’t necessarily exist in every browser) by using jQuery, none of the subsequent callback Read more…
Sometimes I want to be able to write code like the following so that I can substitute a placeholder for a given substring: In order to get the above code to work, I wrote the following function: This function will take an arbitrary amount of arguments and return the string Read more…
The answer to last week’s Problem of the Week is that the following definitions represent the factorial of the given non-negative integer: Mathematical Definition Function Definition Condition unnamed(n) = 1 if n = 0 n × unnamed(n – 1) if n > 0 JavaScript Definition Although it may have been Read more…
This Problem of the Week involves determining the identity of a well-known mathematical function by examining the algorithm used on the input number to produce the output. The function will only accept integers that are greater than or equal to zero. The following is the mathematical definition of the function: Function Definition Condition Read more…
New & Improved Definition Last year I wrote a version of this function which was to mimic the Python expandtabs function. The funny thing is I didn’t remember that I wrote the function in the first place. Therefore while working on a project, I wrote the following function which is Read more…
