What is SWC? swc (opens in a new tab) (speedy web compiler) is a super-fast JavaScript compiler. What can SWC do? It can transpile TypeScript / jsx / ECMAScript 2019 to browser-compatible JavaScript. // input.js class Foo { set foo(v) {} } class Bar extends Foo { get bar1() {} async bar2() {} } How fast is SWC? It's 16x - 20x faster than babel even on single-core synchronous benchmark. Note that a
