Why Learning to Code is So Damn Hard | Thinkful

What every beginner absolutely needs to know about the journey ahead.

The four phases of the typical journey into coding

  1. The Hand Holding Honeymoon is the joy-filled romp through highly polished resources teaching you things that seem tricky but are totally do-able with their intensive support. You will primarily learn basic syntax but feel great about your accomplishments.
  2. The Cliff of Confusion is the painful realization that it’s a lot harder when the hand-holding ends and it feels like you can’t actually do anything on your own yet. Your primary challenges are constant debugging and not quite knowing how to ask the right questions as you fight your way towards any kind of momentum.
  3. The Desert of Despair is the long and lonely journey through a pathless landscape where every new direction seems correct but you’re frequently going in circles and you’re starving for the resources to get you through it. Beware the “Mirages of Mania”, like sirens of the desert, which will lead you astray.
  4. The Upswing of Awesome is when you’ve finally found a path through the desert and pulled together an understanding of how to build applications. But your code is still siloed and brittle like a house of cards. You gain confidence because your sites appear to run, you’ve mastered a few useful patterns, and your friends think your interfaces are cool but you’re terrified to look under the hood and you ultimately don’t know how to get to “production ready” code. How do you bridge the gap to a real job?

Which phase are you in?

      Test driven development. It’s a technique where you know what behaviour or result the code should produce, but you haven’t written any producing code yet. So you break down the problem into small steps which each produce a testable result or behaviour that brings you closer to what you need. And before writing any implementation for each of these small steps, you write a unit test which checks whether an implementation would execute this step correctly. Once you have each test set up, you can start writing the implementation, keeping it as simple as possible, and running the test until it passes for your implementation. This keeps going in a cycle.

      Once all your tests pass, provided you’ve written good and correct tests for every step, there are several benefits of this approach:

      • you can be quite confident that your code works as expected
      • making changes to existing code is much less scary, because you can change the thing you need to change, adjust or add tests accordingly, and rerun all the other tests to make sure everything else still works as expected
      • there is a big psychological benefit when you force yourself to define exactly what you expect the code to do before you actually write it
      • it can help others understand what the intent behind the code is by looking at its expected behaviour

      The downside is that it takes more time to write tests for everything. But for complex applications, it will save you a lot of time in the long run if the code will be changed very often in the future or is complicated, because many bugs will be caught by your test landscape.

        Sometimes ill do TDD, sometimes ill do the opposite. When I know what something looks like or should function. Im not sure what the technical term of itis, but ive heard someone call it Scaffold testing. Its making sure all the parts work as expected (Unit and integration/e2e) for your future sanity.

        TDD lets you experiment and makes multiple potential solutions to a general problem. IE starting with the end first. Scaffolding lets you create a scaffold around what you already built so its more rigid. Both have their place.
