One of the most notable additions in ECMA 2023 is improved support for functional programming. New higher-order functions, such as
compose, will make it easier to write functional code that is more readable and composable.
Another major addition in ECMA 2023 is new syntax for destructuring and spread operators. This will allow developers to more easily extract values from objects and arrays, and to spread elements of an array into a new one.
Additionally, ECMA 2023 brings additional support for async/await, which will make it easier to write asynchronous code that is more readable and maintainable.
ECMA 2023 also adds improved type inference with new type annotations, which will help developers catch type-related errors early on in the development process.
The new version also brings better support for modules and imports, which will make it easier to organize and reuse code across different parts of an application.
