Mathematical Substitution

Run code step-by-step inline
In collaboration with Robert Haisfield


In order to use functions, developers need to understand what they do, especially if they are learning to code. But "Go to definition" takes the developer out of their context, and requires them to simulate and create a mental map of the codebase. By replacing code in place it could help developers understand the code better.
