To really feel comfortable learning any language there are four main areas you need to start with.
What types of data can my variables be, how do I declare the variable? What operators are available to do mathematical and boolean operations with my variables?
What collections are available to group my data like arrays, objects, maps, tuples, etc.?
How can I make conditional code? (ifs, switches, ternary)
How can I repeat code? (while and for loops)
How can we encapsulate code into a function I can call when needed?
How do I pass parameters to that function?
How does that function return a value, what if it doesn't?
What's a pure vs impure function?
How can I encapsulate data and functions into a class (if possible)?
How can I define what occurs when an instance of the class is created and destroyed? (constructors/destructors)
How can a new class borrow the structure of a class already created? (inheritance/polymorphism)
How can I alter the structure from the borrowed class into the new class? (overriding)
Once you learn these concepts it is just a matter of applying a particular language's nuances and syntax to these concepts. Below is a coding exercise that will help you practice all the above.
- Create a fighter class
- each fighter should have a name, health, strength and defense attribute
- each fighter should have an attack method and defense method
- use randomization to set each fighter's stats and to randomize the effects of the attack and defense methods
- instantiate two fights
- create a loop in which the two fighters will fight till one's health is depleted
repeat this exercise for each language you learn.
below are playlists I've made teach the basics for several programming languages:
