Probably a good idea. I decided to learn Rust after using Python for a couple years. I took a semester of C++ but barely remember anything. Maybe I should write a project in C and rewrite later in Rust. I personally only learn when I get inspiration to make a program, which means I learn on the spot. I don’t think it is the best way to do things (if I knew the language better I may make better decisions), but it is the only way I can motivate myself to learn.
