The ecosystem will have to demonstrate the data. If a line of code computes a point, that issue needs to be immediately seen.
Mastering cooking is just not about guessing the features of one's kitchen area appliances. It is really about comprehending how ingredients may be blended.

The instance earlier mentioned permits the programmer to observe the program's execution as time passes. But she's peeking by way of a pinhole, only seeing one level in time at any instant. She has no visual context.
Absolutely concrete code can be micromanaged -- the programmer has express control above just about every phase from the execution. Abstraction usually means offering up many of this Management, and This may be scary for any learner.
The ecosystem need to dump the areas bucket onto the ground, enabling the programmer to constantly react to her Uncooked content and spark new Concepts.
In the following case in point, the program circulation is plotted on a timeline. Just about every line of code that's executed leaves a dot at the rear of. The programmer will take in the complete stream at a look:
