To answer last week’s POW, the purpose of the SQL was to generate a random string of letters and numbers. I actually wrote two different JavaScript function that can produce the same results. The following is the slightly more straight-forward solution: The next version is a bit harder to follow Read more…
This answers the Problem of the Week from May 8, 2012. The identity of this well-known computer science function is the binary search. The following is the same code from before with the variables more properly named: To tell you the truth, after using the real names in the function Read more…
This Problem of the Week involves determining the identity of a well-known computer science function and renaming the variables so that the definition makes more sense. The following is the function definition (obfuscated by me): What I can tell you is that this function takes in a sorted array (in ascending order) as the Read more…
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…
There have been many times when I needed a way to define a function (or variable) only if it wasn’t already defined. Since this seems to be such a common situation, I decided to write a function which will only define a variable, in a given namespace if a definition Read more…
One thing that most JavaScript writers do now, which is a good practice, is they create namespaces for their functions and variables. The following is a definition for a function that can be used to easily create namespaces of any depth: I have to admit, this idea is not originally Read more…
That’s right! As of right now, I have a totally open source, unbreakable encryption tool available to the masses called Crypter. What Is Meant By Unbreakable The only way that I can conceive of breaking any of the encryption methods used in the Crypter is to actually know the key Read more…
The following answers the Problem of the Week from May 14, 2012: At first glance, it may seem that the following would be the solution: Unfortunately, the above results in true being returned. In order to get false to be returned, you could do the following: Even though the result Read more…
Many JavaScript/JScript developers use Google Closure Compiler to compile their code. Even though this tool is a great way of minifying JavaScript code, believe it or not, it doesn’t always work (at least as of May 14, 2012). The following JavaScript code works fine when you run it without being Read more…
Instead of rewriting the article myself, I figured it is better to simply link to it: http://mislav.uniqpath.com/2010/05/semicolons/. After reading this article, do remember that just because it is stated that they are not needed doesn’t mean that it is bad to include them. 😉
