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…
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…
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…
In this post I proved that the String.prototype.split function can behave differently in IE8 and below than it does in other browsers. For that reason, I wrote the following code that will fix the issue so that split should work the same in all browsers: It is important to note Read more…
At times I use the String#split function in order to create an array from a string based on a RegExp delimiter. Unfortunately, today I realized that some browsers act differently than others. Let’s consider the following example: In most browsers, the value of the above variable would be true which Read more…
