WARNING: Extending native prototypes is frowned upon by many JS engineers but can be helpful as long as the extensions are properly documented in the codebase. SCRIPTER’S DISCRETION IS ADVISED. 😆 Even though its NOT encouraged to extend native prototypes, at times you may find that doing so is pretty Read more…
One of the great things about reading through Douglas Crockford’s site is that you get to learn about how certain things like prototypal inheritance was implemented prior to ECMAScript 5. Since then Object.create() made its way into JavaScript and has been available in most modern browsers for a while. If Read more…
As I mentioned in yesterday’s post, I was recently working on a quick way to parse CSVs into an array of arrays and alternatively into an array of dictionaries keyed on the values in the first row. I ended up landing on the following definition: As you can see the Read more…
A few days ago I was working on a very primitive version of a CSV reader for a quick JS project and while testing my regex out, I noticed that I was getting an extra match at the end. Here is the JavaScript function that I had: Interestingly, if you Read more…
Last year I wrote about having heredoc like strings available in JavaScript. Today I figured i’d briefly bring the topic back, providing a solution for returning an array of all comments found in a function: Why is this useful? As you may know, writing multiline strings in JavaScript isn’t always Read more…
Most of us know the simple way to get the keys from an object in JavaScript (~61 bytes after minified): But how many of us knew that array assignment within the for-in loop would work? (~58 bytes after minified) To be honest I cant take the credit for this because Read more…
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…
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…
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…
