Having become familiar with the LEX Institute’s theory that learning more than one human language at once leverages learning them all, through its Who Is Fourier? (a book), I’m now on the lookout for “dynamic duos” or “combos” which heighten our ability “compare & contrast” while tackling both.

JavaScript front burner, with Python back, or switch front and back (in terms of emphasis), may be a faster path to mastery than either all alone. We learn from the differences and similarities, which accelerates the whole process.
