Book Review: JavaScript: The Good Parts
Although, JavaScript: The Good Parts is nearly ten years old I would argue it’s still a pretty good book to read. Literally, as the title implies the book calls out the best parts of the javascript language and tells what parts of the language to avoid.…
What is ORM?
Most software projects need to talk to a database at some point – they usually do GET queries for data, update a field or create a record. In the past, people would write raw code that communicated with the database and built an object or some code representation of the data that they would manipulate. This lead to an incredible amount of duplicated code for every project that usually had some subtle bug that was present in all libraries. …
What is a Self Invoking Function
In JavaScript, it’s common to hear lots of strange terminology without a lot of description around what it is or what it does. I want to try and demystify what a self invoking function is and why you should consider them and the times when maybe you shouldn’t consider them.…
Why JavaScript
In the earlier days of the web, there was a battle between two scripting languages VBScript and JavaScript. VBScript, thankfully, eventually died and JavaScript became the dominant language for making really easy to use and interactive websites.
In the years since, JavaScript has become more and more used. Backend code can be written in basically any language, even in JavaScript, but the client side will almost always require a developer with some JavaScript knowledge. Every industry has a lot of javascript and some are even rewriting core functionality to use more. Surprisingly, even large banks and credit card companies are beginning to use JavaScript or Node in big ways. PayPal has been rewriting very large parts of their code base to make it more scalable and usable.…
How to Use Reduce on JavaScript Arrays
In functional programming, being able to reduce is one of the fundamental concepts. Reduce is used to iterate through the values in an array and condense all of the values into a single value. Usually the value is a sum of all of the elements, but it could be used to decrement, multiply or even…
Detecting Inactivity in JavaScript

Updating Salesforce Records Using JavaScript

Recreating PHP’s time() function in JavaScript
PHP’s time() function returns the current unix timestamp. JavaScript doesn’t exactly have the same functionality, but it’s pretty close. Put a different and more understandable way, it returns the current time measured in seconds since the Unix Epoch (00:00:00 UTC on 1 January 1970).
JavaScript has a similar way of getting the time but it’s in milliseconds since the Unix Epoch.
JavaScript IsNumeric Function
In the past, there’s been so many times I needed to tell if an object was numeric. With the below function, it’s very easy to tell if an item is numeric. If your project is already using jQuery, you could always use jQuery.IsNumeric()

Dealing With Dates in JavaScript
Dates and DateTimes are difficult to deal with in most languages. The Date object is a datatype that’s built in the JavaScript language. In JavaScript, the biggest problem is that the browsers aren’t overly consistent in the way they have implemented the Date object and its APIs. …
Disabling Caching on All AJAX in jQuery
It’s no secret that many of us that use javascript regularly love jQuery because it handles a lot of the cross browser issues and makes our lives so much easier. The .ajax function makes use of caching by default, but we can override this by creating a function called .ajaxSetup and adding cache: false in…
