Effective TypeScript: 62 Specific Ways to Improve Your TypeScript

TypeScript is a typed superset of JavaScript with the potential to solve many of the headaches for which JavaScript is famous.

Author Dan Vanderkam, a principal software engineer at Sidewalk Labs, shows you how to apply these ideas, following the format popularized by Effective C++ and Effective Java (both from Addison-Wesley). You'll advance from a beginning or intermediate user familiar with the basics to an advanced user who knows how to use the language well.
