core-js is a modular standard library for JavaScript, which includes polyfills for ECMAScript up to 2021. It's often used in conjunction with Babel to polyfill newer JavaScript features in older environments. Unlike @babel/preset-env, core-js does not handle syntax transformations but focuses on providing polyfills for language features.
esbuild is an extremely fast JavaScript bundler and minifier. It can compile modern JavaScript syntax to older versions for compatibility purposes, similar to what @babel/preset-env does. However, esbuild is more focused on the bundling aspect and aims to be a more comprehensive build tool rather than just a transpiler.
TypeScript is a superset of JavaScript that adds static types. The TypeScript compiler can also downlevel modern JavaScript to older versions, similar to @babel/preset-env. However, TypeScript's primary focus is on type safety and it requires type annotations, whereas @babel/preset-env is purely about compiling newer JavaScript syntax to older versions.
