If you've used Knockout.js in your project, at some point or another you've probably encountered the following error "Uncaught ReferenceError: Unable to process binding". The most likely cause is a typo somewhere or forgetting to change the context. E.g. you are within a foreach binding and forget to use $parent.

I recently encountered this issue and could not find the typo anywhere. Like most developers in my situation I was getting really frustrated, banging my head against the world looking for answers. Luckily I was able to use this Knockout.js tutorial to narrow down and solve my problem.

Unfortunately, there is no easy answer to this bug; however, I can suggest an excellent technique that will hopefully help point you in the right direction.

Here is a complete example that creates a table and displays a list of books within the table. There is an unfortunate typo within one of the td data bindings.

Including a JavaScript file into another file is a very nice thing to be able to do. It's something you probably do with almost every other language; it helps keeping files smaller, more readable, and of course, more readable. There are multiple ways to accomplish this and I'll let you pick the one that works best for you.

Many people "dislike" JavaScript for reasons that I cannot understand. I like it and it serves a purpose. JavaScript can be a very forgiving language. By that I mean it let's you get a way with things that other languages, that are a little stricter, would not. This is where the "use strict" comes into play.

I honestly feel like I've been living in the stone age. For years I've always used a standard for loop when iterating a JavaScript array accessing the property with the index of my for loop. No longer, it's time to upgrade (my brain) and use the forEach loop.

It's quite common to redirect a user visiting your webpage, more specifically when they perform an action, such as: clicking a button. When the user completes the action and you want to redirect the user to somewhere else, you have two common choices:

window.location.href = '';

OR

window.location.replace('');
