One thing I have been doing for quite a while is using equality to (==) undefined or null to check if something is equal to one of those two values. Unfortunately, if your JS code needs to pass a linter, this type of check is not acceptable. On the other Read more…
At first I thought this was an infinite loop bug issue. After that, I thought it was just simply a bug. Now, after a co-worker (Geoff) pointed me to the JavaScript specs, I see that Chrome implemented this correctly and others didn’t. In most browsers the following code would result Read more…
First of all, i’m sure that the title is a bit confusing, but I couldn’t think of a good way to state in a few words the scope of a solution I was looking for today. Basically, I had a list of dictionaries and I wanted to create a new Read more…
Often times in JS it is necessary to trace through someone else’s code (or your own 😉 ) to determine the root of a problem. Many times I have found that knowing how a function was called in the first place can be very helpful. Since I use Chrome for Read more…
When analyzing data in Excel at times it is necessary to pull data from another data source based on more than one column. In this case you can use the MATCH function in an array formula. Just so you understand the general idea of an array, it is a collection Read more…
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…
Today I was writing some code in which I wanted to modify the values of an array within a for-loop. The obvious solution would be to use the key to modify the value but there is actually another way of doing it: The above code will actually go through 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…
