I haven’t covered any advanced topics until now – functional programming in Javascript is an advanced topic in my book. Not only is functional programming an advanced topic, it’s quite special and specific to the Javascript language. Even a well seasoned developer could get a little frazzled by the concept of functional programming – especially those who code in more statically typed languages – like C or Java.

I, myself have mulled over this a long time – especially because I haven’t built any applications using much of functional programming. Frameworks and libraries – yes, but I’m talking about writing my own proprietary code. Programmers unknowingly utilize functional programming all the time – with this, comes closures, prototypical inheritance – other advanced patterns found in our javascript libraries today.

I’ve been mulling over getting this post up for a while now – simply because functions are a big deal in Javascript. Javascript functions are packed with so many properties, methods and it’s fundamental nature requires some quality time in understanding its features.

There are a few things to keep in mind when dealing with Javascripts call(), apply, and bind methods()

• call(), apply() and bind() are three methods every function has access too
• bind() creates a copy of the function object in question
• call(), apply() and bind() methods are methods that allow an object to point to a different ‘this’ variable when invoked.
• Common patterns used in conjunction with call(), apply() and bind() are function borrowing and function currying.

Javascript’s typeof operator is an essential debugging tool that many young programmers often miss. Countless times I’ve run into situations where my program wasn’t working because either my variable was unnoticeably coerced or I was just completely unaware of a data type. As mentioned in a previous post – a season programmer should know their data types! Another thing a seasoned programmer ought to know is to prevent themselves from being too arrogant – yes, we need help and using the “typeof” operator is there to the rescue.

This is part || of Data Structures & Algorithms using Javascript. I would like to give credit to freeCodeCamp.org for their series of videos covering this topic.

In part I we started off with a simply defining a few data types – an array and a string for storing data in memory. Then we used a “for-loop” to access and manipulate our data structures. Finally we came up with a sequence of steps to test whether a word was a palindrome or not. In part II now, were going to wrap up all that code into what we call a function object.

Functions are a powerful data structure encapsulating your algorithms. Functions also are a good example of “DRY” – Don’t Repeat Yourself.

Javascript is a language most developers either overestimate or underestimate – whatever the case, this is what makes Javascript special. Javascript is a dynamic language, it’s abstract and for this reason also prone to instability. Javascript in the last decade has provided developers with a place for inventiveness and innovation.

Lately I’ve been immersing myself into mathematics, physics, chemistry, philosophy and even linguistics. I found my premise to still hold true – that the universe is at a state of decay, of disorder, and mutation. It’s exactly because of mutation that we are able to manage disorder and chaos, so in a sense we are constantly trying to keep up with ourselves as we simultaneously and inevitably push forward into the future.
