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('');

This is not something I use everyday. Seems more like a once a year thing. Last time I needed to extract query string variables, I used the old school approach with a regular expression. Now that I need to do this again, I can use the new school approach: URLSearchParams.

The URLSearchParams (at the time of writing) is not yet standardized in the W3C; however, most modern browsers recognize it.

This morning I had to format a date using JavaScript as follows: yyyymmdd requiring both the month and day to include a leading zero when the month or day was less than 10. This solution using slice multiple times.

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.

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.
