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.

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…
It has been a while since I wrote a JavaScript utility function so a few minutes ago, I had the idea to create a function which will allow you to set the default value of a parameter for any given function. After writing the following function, I thought about the Read more…
There have been many times when I needed to simply modify the flags (options) for a regular expression in JavaScript. Unfortunately, the global, ignoreCase, multiline, and sticky (for FireFox) flags are immutable. In addition, when creating a new regular expression from an old one, you can’t supply a regular expression Read more…
I was writing two HTAs (HTML Applications) today and for the first one, I needed to create a VBArray with the number five in it. Fortunately, I remembered that I wrote a page about this prior to my blog. Therefore, here is the snippet which I plan on including in 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…
The following is a function which returns the chainable version of a function: Here is an example of how to define a pseudo-class which uses this chaining method: Here is an example which shows that the chaining works as intended:
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…
The following is a quick JavaScript function which can determine if a string contains a substring: The above function is a function that, once defined, will exist for every string. The first parameter, which is the string to be found, is required. The second parameter, which is a boolean specifying Read more…
