Are there any comparable features in JavaScript and TypeScript that mirror Julia's metaprogramming and macros?

Having experience with Julia macros for metaprogramming, I find them to be a convenient way of generating versatile code.

I'm curious if there is an equivalent approach in JavaScript or TypeScript. Is there a package or method that offers similar functionality?

Answer №1

Unfortunately, neither ECMAScript nor TypeScript currently support macros.

While there is a proposal for Decorators that aims to provide similar functionality to macros, it is still in the early stages of development.

Although there are no official proposals to add Macros to ECMAScript, the idea has been discussed due to the influence of Scheme designers on the committee.

In the ECMAScript community, the use of source-to-source compilers like Babel is common to achieve similar results as macros in languages like Julia, Scheme, Rust, Boo, and Nemerle.

Third-party libraries like Sweet.js do offer some macro capabilities through source-to-source transpilation for ECMAScript.
