Like TypeScript, it can integrate with JavaScript libraries “as-is”, which means some of the types won’t always make sense, nor are they consistent, or they may be overly complicated because of the way the JavaScript library was designed. ReScript’s types are powerful, but like TypeScript can get pretty deep, quickly. Early Strugglesĭespite it’s much cleaner syntax compared to TypeScript, I still struggled to make a lot of headway in learning Reason/ReScript. My hope is it will inspire you to check out what ReScript has to offer compared to TypeScript. I wanted to cover what I’ve learned in the past 2 years, and even this weekend. I spent the past couple of years playing around with Reason, which later split off into ReScript: the OCAML for JavaScript developers.
