The title says it all. I have many great ideas to do with crypto in general but lack the ability at the moment to code them how I would like.

Can anyone point me in the direction of a good tutorial for beginners so I can start to learn how to code?

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, but full nodes are more resource-heavy, and they must do a lengthy initial syncing process. As a result, lightweight clients with somewhat less security are commonly used.
Advertised sites are not endorsed by the Bitcoin Forum. They may be unsafe, untrustworthy, or illegal in your jurisdiction.

The question is do you really want to start learning that?
There is no 'best' place? What factors are deciding for something to be called a 'best place' ? You could pretty much Google this and find your answer, couldn't you?

In my opinion, actually making a website is the best way though. After you finish some projects on codecademy make a bitcoin related website, using daemons and such, and you learn well that way.

I really think it depends on what level you're starting from.  If you have a strong learning in data types and algorithms and how computers work then you probably can just get started with the syntax and specifics of javascript.  If, however, you've never written any code before then you probably need to start with basics about how computers work, how data is stored and manipulated, what are the basic datatypes and how do programming languages allow you to manipulate them.

Great! I've been using code academy and so far the website is great!
Although I am stuck on the stupid orange price part.. :/

The lesson is seen below (sorry for terrible formatting)

Don't Repeat Yourself (D.R.Y)
The D.R.Y. principle is really important in programming. No repeating!

Any time you find yourself typing the same thing, but modifying only one small part, you can probably use a function.

The 'small part' that you find yourself modifying will be the parameter. And the part that you keep repeating will be the code in the reusable block - the code inside { }.

Instructions
You are a creature of habit. Every week you buy 5 oranges. But orange prices keep changing!

You want to declare a function that calculates the cost of buying 5 oranges.
You then want to calculate the cost of the 5 all together.
Write a function that does this called orangeCost().
It should take a parameter that is the cost of an orange, and multiply it by 5.
It should log the result of the multiplication to the console.
Call the function where oranges each cost 5 dollars.
?
Hint
What is the one bit of input that changes each time? It would be the price. So give your parameter the name price. And when you call your function, put in a number for the price to see how much 5 oranges cost!

Now. What I have coded looks like this:

var orangeCost = function(price){
    console.log(price*5)
};
   orangeCost = 5


I am stumped. :/
