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…
Today, I had to figure out a way to parse an HTML string in Python in order to find all of the attribute values of attributes starting with a specific string. Since we already have BeautifulSoup installed, I started researching how to use a lambda function in conjunction with the 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…

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…

One simple function that is on the roster to be released in EcmaScript 6 is String.prototype.repeat. The following can be used to define it in browsers which don’t currently have it defined natively: Here are some examples of using this function (modified from the originals found on MDN): There is Read more…
Now Available in YourJS At times you may need to format a string so that it is more appealing. One function that does this is String#toProperCase() because it actually capitalizes the first character of each word. Even though I already had a simple version of this defined in jPaq v1 Read more…
One string method that I found today in Python is the count function to determine how many times a given substring appears in a string. Below is the equivalent of this function in JavaScript: It is important to note that if you pass a regular expression as the target instead Read more…
One thing I needed to do recently was indent a series of strings with a variable number of tabs or spaces. Thusly, I decided to create the following function which can be used by anyone that would need such a function: The JS annotation pretty much sums up how you Read more…
