A while back, I wrote a function about Solid Type Checking. What is funny is that I often am writing just a bit of JavaScript in which I need a better way of checking the type of an object or primitive. Unfortunately, since I have been slacking on the next Read more…
Recently at work we had the need to convert a string parameter (passed into an iReport) into a table. For many people, the first thing that may come to mind is either the STRING_TO_ARRAY(...) function combined with the UNNEST(...) function. The biggest issue with using just those two functions is Read more…
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. Read more…
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…
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…
Yesterday, I posted about creating String.prototype.indexOfIter() which basically returned a function which would act as an iterator function, indicating the indices of the specified substring. What I neglected to include was how to write this solution using JavaScript 1.7 in FireFox. Today, I bring to you the equivalent using a Read more…
One of the cool things about JavaScript 1.7 is the fact that it supports generator functions. Unfortunately, not all browsers support generator functions yet. Therefore, when creating iterators we can look to an interesting alternative: closures. For example, if our goal was to make a String prototype function which would Read more…
Recently, I have been interested in creating a quick one-way encryption method. After playing around with a lot of different variations, I settled on the following: One nice thing about this function is the fact that you can restrict the encrypted message to a certain length. Another interesting thing is Read more…
The following prototype function mimics the hashCode() function of java.lang.String in Java: Depending on the version of Java that you are running, what is returned from this function may not be the same thing that is returned in Java. On the other hand, this implementation is computationally equivalent to the Read more…
The following is a quick JavaScript function which will return the reverse of a string: The above function is a function that, once defined, will exist for every string. Here are some examples of how to use the above function: By the way, if you noticed the last two examples Read more…
