Programming tutorials for people who want code that actually runs, not code that only looks right. Pick a language, start at the beginning, and don't skip the basics. They are where most problems come from.
This is for people who already write basic JavaScript and want the compiler to catch wrong data before the code runs. You will add types to JavaScript you already know, compile with tsc, and stop guessing what a function accepts. If you skip the basics and add any until the red lines go away, you keep the old bugs and add a build step.
