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: function uncamelize(s) { return s.replace(/[A-Z]/g, 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: String.prototype.repeat = String.prototype.repeat || function(count) { return Array(count >= 0 ? parseInt(count, 10) + 1 : -1).join(this); 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: String.prototype.count = function(target, start, end) { start = start || 0; end = end == null 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: /** * Indents the given string * @param {string} 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: (function(split, toString, slice) { String.prototype.split 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: var splitWithRegExpWorks = ','.split(/,/).length == 2; In most browsers, the value of the Read more…
If you have ever taken an encryption class, I am sure that you have heard of the Vernam Cipher. For fun today I decided to write a quick one in JavaScript which takes your message and the random key: function vernam(msg, key) { var l = key.length; var fromCharCode = Read more…
Nearly a year ago I wrote a quick post about the awesome heredoc notation for strings in many languages such as PHP: $query = <<<QUERY SELECT * FROM table WHERE col_1 = val_1 AND col_2 = val_2; QUERY; Unfortunately, this doesn’t exist in JavaScript. If for some reason you do Read more…
A few days ago someone asked me how I would go about determining the unicode escape sequence for an arbitrary character. Of course, I went to Google Chrome’s web console and showed them how it can be done by using the charCodeAt, toString, and slice functions. The following is a Read more…
