Introducing ReScript 12

Learn ReScript for building modern web applications. This concise guide uses clear examples and explanations to walk you through ReScript s core concepts while leveraging existing JavaScript experience.

This new edition incorporates the latest features from ReScript 11 & 12, including uncurried mode, updated record types, async/await support, and new syntaxes. You ll learn how to use features in ReScript that JavaScript lacks, such as type inference, null-safety, algebraic data types, pattern matching, and more. Along the way, you'll pick up functional programming concepts like immutability and higher-order functions. You'll also gain a sense of how ReScript works under the hood and how to leverage interoperability between ReScript and JavaScript.

Whether you're a web developer interested in dabbling with functional programming or you just want to learn how to write safer and cleaner code for web applications, this book is a great way for you to get started with ReScript.
