One of the major changes in ES2025 is the introduction of pattern matching, which is a powerful feature that allows developers to match values against patterns and perform different actions depending on the results. This feature is similar to the
match syntax in Rust and the
case statement in Scheme and other Lisp dialects.
Another key feature of ES2025 is the addition of tail call optimization, which allows for efficient recursion and improved performance in functional programming scenarios. This feature is similar to the
call/cc function in Scheme and the
trampoline function in Lisp dialects.
In addition, ES2025 introduces a new syntax for lambda functions, similar to the
lambda keyword in Scheme and other Lisp dialects. This makes it easier for developers to create anonymous functions and pass them as arguments to other functions.
Furthermore, ES2025 brings the concept of algebraic data types, which allow developers to define complex data structures in a more expressive and powerful way. This feature is similar to the
data keyword in Scheme and the
define-type function in Lisp dialects.
