The TypeScript progression ladder (TSPL) is a grouping of concepts and skills relevant to TypeScript programming.
TSPL provides aspiring TypeScript programmers with a way to track and improve their TypeScript skills.
Please check it out at http://ladder.ts.training/ and help me to improve it on Github!
UPDATE: One of the main pieces of feedback was that people would like to see a similar concept in other programming languages so I have created an upgraded version that allows people to contribute more lists. Please check it out at http://www.techladder.io/
